Jürgen Popp
Presentation: Translational Clinical Biophotonics
Friedrich Schiller University of Jena
Scientific director of the Leibniz Institute of Photonic Technology
The growing incidence of cancer and the emergence of drug-resistant infectious diseases present urgent challenges to modern medicine. Timely and precise diagnostics, paired with tailored therapies, are crucial for improving patient care. Spectroscopic techniques— particularly Raman spectroscopy—have shown remarkable potential to deliver molecularlevel insights for clinical diagnostics. However, to bring these technologies into everyday medical use, highly reliable and user-friendly optical systems with elevated Technology Readiness Levels (TRLs) are essential. This presentation will delve into recent progress in multimodal spectroscopic technologies that aim to bridge the gap between research and clinical application. Focus will be placed on the development of novel, label-free diagnostic tools, such as Raman fiber probes, clinically viable nonlinear microscopes, and advanced endospectroscopic devices. These instruments support real-time intraoperative guidance and tissue assessment under in vivo or near in vivo conditions, enabling accurate tumor detection, staging, and grading—critical for initiating personalized treatments. Beyond oncology, we will present innovative applications of Raman spectroscopy in managing infectious diseases. Key advances include: 1. Real-time monitoring of immune response, 2. Rapid identification of pathogens and detection of antimicrobial resistance, 3. Dynamic evaluation of therapeutic efficacy. These methodologies span the entire diagnostic continuum, from sample acquisition to clinical decision-making, significantly reducing diagnostic timelines compared to traditional microbiological workflows. To further enhance clinical translation, we will showcase the integration of AI-driven spectral analysis tools. These algorithms transform complex spectral data into actionable diagnostic markers, improving both precision and reproducibility. Finally, we will address infrastructure strategies designed to overcome translational barriers—commonly referred to as the “valley of death”—ensuring that these innovative photonic technologies reach routine clinical use. By aligning cutting-edge biophotonics research with real-world medical practice, this work aims to redefine diagnostics and patient management in both oncology and infectious diseases.

Luciana Kassab
Presentation: Waveguides with different architectures based on GeO2 and TeO2 using Si technology and fs laser irradiation: a review
Professor of Physics at Faculdade de Tecnologia de São Paulo - Centro Estadual de Educação Tecnológica Paula Souza
The search for new materials doped with rare earth ions and metallic nanoparticles has grown due to several applications. In particular GeO2-PbO and TeO2-ZnO hosts are potential candidates for photonics: they have linear and nonlinear refractive index, wide transmission window (400-500 nm) and low cutoff phonon energy with respect to silicates; photoluminescence enhancement due to localized plasmon effects was also demonstrated in these hosts as well as nonlinear optical properties. The Si technology is used to fabricate the SiO2 pedestal; then by the sputtering technique the thin film is deposited on the pedestal to form the core of the waveguide based on Nd3+ doped TeO2-ZnO for applications at 1064 nm. The advantages of the pedestal architecture with respect to rib waveguides are discussed. The other architecture is based on waveguides written directly in Nd3+ doped GeO2-PbO glasses using the fs laser irradiation for the production of a new platform. In this case the glass is produced by the well known melt quenching technique and the double-walled waveguides consisting of a pair of parallel walls (separated by 10 µm) each one created through the superposition of several tracks generated by overlapping laser pulses. Both waveguides (thin films and bulks) are investigated with metallic nanoparticles, that promote the relative gain growth that depends on the amplified spontaneous and stimulated emissions. The increase of the local field in the proximity of the nanoparticles enhances the density of the excited Nd3+, and favours both mechanisms that depend on the concentration of the excited ions. So, it is the population enhancement that is in the excited state that impacts positively the waveguide performance. The present results open new possibilities for integrated photonics and can be extended to different hosts and rare-earth ions
Keywords: fs laser irradiation; Si technology; waveguides; nanoparticles

Timur Labutin
Presentation: Laser-Induced Breakdown Spectroscopy: Expanding from Extreme Environments to Routine Natural Sample Analysis
Associate Professor at the Lomonosov Moscow State University
Laser-Induced Breakdown Spectroscopy (LIBS) is one of the most promising techniques for rapid, direct atomic emission analysis of natural samples, including in situ and field applications. The method uses focused high-power laser radiation to generate plasma on the surface or within the volume of solids, liquids, or gases. The plasma emission is then analyzed to determine the elemental composition. LIBS offers several key advantages: minimal sample preparation, remote measurements capabilities, and robust instrumentation suitable for operation in complex and extreme environments. A comprehensive overview of LIBS applications will be presented. The unique features of LIBS have enabled remarkable applications such as in-situ elemental analysis in the ocean at depths of up to 3000 meters, as well as on the surface of the Moon and Mars. Building on these achievements, and propelled by advancements in laser and spectrometer technologies, LIBS is increasingly becoming a routine tool for analyzing a wide range of terrestrial materials—including soils, ores, minerals, and biological samples. Special attention in this talk will be given to the growing role of LIBS in agriculture. The technique is now being applied for rapid assessment of fertilizers and for evaluating essential nutrients in soil. In addition, LIBS combination with other laser-based methods is being developed for comprehensive analysis of plant and animal tissues.

Presentation: From Fundamental Light Interference to Quantum Communication: A Journey Through Modern Optics
Professor at Universidade SENAI CIMATEC and the Technical Lead of the Experimental Quantum Optics Group at QuIIN
Free-space optical links are essential for the scalability of quantum networks. They enable node interconnection without fiber infrastructure, supporting deployment in ground-based systems, drones, and satellites. However, atmospheric turbulence introduces wavefront distortions and intensity fluctuations that degrade the performance of quantum key distribution protocols. We discuss the main challenges in long-distance free-space links, focusing on beam divergence, beam wandering, and scintillation. Mitigation strategies based on adaptive optics are also explored, highlighting their potential to compensate for turbulence-induced phase aberrations and enhance channel stability.

Presentation: From Fundamental Light Interference to Quantum Communication: A Journey Through Modern Optics
We live surrounded by natural and artificial optical phenomena—the latter used to provide comfort and enable scientific and technological advances. At the core of all this lies the interaction between radiation and matter. Today, with the advent of second-generation quantum technologies and our increasing ability to manipulate quantum states of light (such as laser or single-photon sources), fundamental questions about the nature of light and its interaction with material media have become central to developing cutting-edge technologies. In this talk, I will present recent developments from our group that address both fundamental and applied aspects of light-matter interaction. Specifically: 1- We demonstrate that all electromagnetic wave interference phenomena can be fully described within a quantum and corpuscular framework, eliminating the need for classical wave equations derived from Maxwell’s theory. For instance, we show that mode-locked pulsed lasers can be understood as continuous streams of photons, whose phase relations create matter-interacting (detectable) or non-interacting (dark) quantum states. 2- I will also present our recent progress in quantum key distribution (QKD), as part of a collaborative effort involving UFSCar, UNICAMP, IFSC/USP, Centro von Braun, UFMG, and UFC. Our main goal is the development of optical and electronic devices based on single photon or attenuated laser sources for secure communication networks.

Presentation: Skyrmions as topological light fields.
Researcher at the Department of Physics and Astronomy at the University of Glasgow, UK
Former president of the Optica Student Chapter of Universidade Federal do Rio Grande do Sul (2018-19)
Skyrmions are topologically protected field configurations that have been observed in condensed matter systems, chiral magnetic systems and nematic liquid crystals, and most recently in optic. Since their initial conception in 2018, optical skyrmions have attracted considerable attention due to their highly reconfigurable properties. Unlike their magnetic counterparts, optical skyrmions are free from energy constraints and therefore allow the investigation of topological stability in its purest form. In this talk, I will provide a definition of optical skyrmions based on their topological model, I will show how which beams can be generated in the laboratory and I will demonstrate how we can characterize them using topological considerations.

Filippo Ghiglieno
Presentation: From Snell to quantum cryptography: the optical fiber that connects the world
Professor at the Federal University of São Carlos (UFSCar)
The optical fiber is the true backbone of the telecommunications revolution. Lying beneath the oceans, buried under cities, and running discreetly beneath our feet, it forms the invisible infrastructure that connects people and systems on a global scale. Thinner than a human hair, it functions as a waveguide capable of carrying terabits of information per second across thousands of kilometers with minimal losses. The journey begins with Snell’s Law, which provided the theoretical foundation for understanding light confinement, and reaches the pioneering experiments carried out in Brazil in the 1970s at the Gleb Wataghin Institute of Physics, Unicamp, where the Quantum Electronics Department produced the first domestically manufactured fiber in 1977. This effort, supported by Telebrás and later transferred to CPqD and the company ABC-Xtal, consolidated optical fiber as the essential physical layer of the OSI stack and as a driving force behind network digitalization. As a protagonist of the first quantum revolution, together with the laser that transformed communications, optical fiber now returns to center stage in the second quantum revolution, serving as the infrastructure for advanced information and security systems. It enabled the global expansion of the internet, supported transmission rates of tens of gigabits per second, and continues to evolve as the backbone of secure, high-speed communications in the 21st century. This talk traces that scientific and technological thread, revealing how science, industry, and society intertwine in a journey that spans from glass to quantum. It further highlights how optical fiber today plays a crucial role in the implementation of advanced, more secure protocols (QKD), paving the way for the internet of the future: the quantum internet.

Presentation: Laser-induced Breakdown Spectroscopy: Afast in-situ technique applied to identify and discriminate grains and seeds of different nature and detect plant viruses
Geologist and researcher at the Italian National Council Research (CNR), Institute for Plasma Science and Technology (ISTP), Bari seat, Italy.
Laser-induced breakdown spectroscopy (LIBS) is a straightforward and adaptable technique of atomic emission spectroscopy based on focusing a short-duration, fast-pulsed laser beam onto a sample, thus producing a plasma of its constituent elements, which are then detected by spectral analysis of the light emitted. LIBS analysis can be performed quickly in-situ in a laboratory setting or outdoors in a natural setting. Depending on the intrinsic limit of detection of each element in each material, LIBS can analyze almost all elements in the periodic table both qualitatively and quantitatively. In particular, LIBS is especially sensitive to the light elements H, Li, Be, B, and C, which are difficult or even impossible to be analyzed by most traditional techniques. The broadband LIBS spectrum can be thought of as a diagnostic chemical fingerprint.
My talk will illustrate how LIBS has been recently used in different applications to: (i) distinguish among batches of soybean seeds of different physiological quality based on their nutrient content; (ii) identify and discriminate different varieties of conventional (not-genetically modified, NGM) maize from varieties of transgenic maize (genetically modified, GM); and (iii) early detect plant pathogens in order to prevent the dramatic impact they may have on plants.
The potential of routine LIBS application across a wide range of agro-photonics sectors is enormous, but it is currently only partially realized. This is due to the necessity of analytical instrumentation for the quick chemical analysis in the field and the ability of LIBS to analyze any type of material (gas, liquid, and solid) in real time with little to no preparation.

Presentation: Thickness-Dependent Second Harmonic Generation in Mechanically Exfoliated 3R-Niobium Disulfide: An Experimental and Theoretical Study
School of Engineering, Mackenzie Presbyterian University
Layered materials, such as transition metal dichalcogenides (TMDs) [1] have been widely explored for second- (SHG) and third-harmonic generation (THG), enabling a broad range of photonic applications such as frequency conversion [2], all-optical processing [3], and light modulation [4]. Niobium disulfide (NbS2) is a Group V layered TMD stabilized in the 3R phase, which inherently exhibits SHG regardless of thickness. Unlike most TMDs, which exhibit a semiconducting nature, NbS2 is metallic. In this work, we investigated the SHG in mechanically exfoliated NbS2 of different thicknesses and compared our results with SHG from CVD-grown monolayer MoS2. Furthermore, atomic force microscopy (AFM) and Raman spectroscopy were employed to determine the thickness and vibrational modes of the investigated flakes, while optical microscopy was used to obtain reflectance and transmittance data in order to probe their optical properties. Polarization-resolved SHG was characterized in transmission and reflection modes using a confocal laser microscopy setup, with 1560 nm, 42 fs, 99 MHz pump laser and signal detection by a grating spectrometer (Andor spectrometer, colled CCD camera model iDus 416). A systematic investigation of SHG as a function of thickness revealed good agreement between experimental results and theoretical modeling. In transmission mode, the SHG intensity exhibited a pronounced maximum for flakes in the 150–200 nm range, followed by a gradual decrease for thicker samples, reaching minimal values above 400 nm. On the other hand, in reflection mode, the SHG response remained significant across almost the entire thickness range, peaking around 300 nm and remaining approximately constant for thicker flakes. This behavior highlights the interplay between constructive and destructive interference, as well as phase-matching mechanisms in layered materials. Furthermore, our comparative study between monolayer MoS2 and NbS2 flakes (65–600 nm) reveals that NbS2 exhibits a second-order optical susceptibility (𝜒2) of the same order of magnitude as monolayer MoS2. These characterizations of the nonlinear optical response of NbS2 highlight it as a promising candidate for next-generation two-dimensional materials-based photonic and optoelectronic devices, including all-optical switching and frequency conversion applications.

Presentation: Use of Photosynthetic Microalgae to Optimize the Photodynamic Effect
Assistant Professor at Faculdad de Física, Pontificia Universidad Católica de Chile, Santiago, Chile
Photodynamic therapy (PDT) is a promising approach for the treatment of infections and cancer, but its effectiveness is limited by its dependence on molecular oxygen. The low oxygenation of tissues, common in infections and tumors, reduces the generation of reactive oxygen species (ROS), compromising the antimicrobial and antitumor action of PDT. In this talk, we present an innovative strategy to overcome this limitation: the incorporation of photosynthetic microalgae into PDT, providing a continuous source of oxygen at the site of action under light exposure. In the treatment of infected wounds, we are developing a hydrogel dressing that combines photosensitizers and microalgae, optimizing light and oxygen delivery directly to the wound. In the oncological context, we explore the use of microalgae to enhance PDT efficacy, both independently and in combination with radiotherapy.
Our studies range from photophysical characterization to in vitro testing, with future application in murine models of infected wounds and tumors. This approach represents a significant advancement in optimizing PDT, opening new perspectives for the treatment of infections and expanding its potential in oncology.

Presentation: Use of multivariate classification algorithms with variable selection applied to biospectroscopy
Vibrational spectroscopy techniques, such as Fourier-transform infrared (FTIR) and Raman spectroscopy, have been successful applied to investigate the interaction of light with biological materials and facilitating novel cell biology analysis. Spectrochemical analysis is very attractive in disease screening and diagnosis, microbiological studies and forensic and environmental investigations because of its low cost, minimal sample preparation, non-destructive nature and substantially accurate results. However, there is now an urgent need for multivariate classification protocols allowing one to analyze biologically derived spectrochemical data to obtain accurate and reliable results. Multivariate classification comprises discriminant analysis and class-modeling techniques where multiple spectral variables are analyzed in conjunction to distinguish and assign unknown samples to pre-defined groups. The requirement for such protocols is demonstrated by the fact that applications of deep-learning algorithms of complex datasets are being increasingly recognized as critical for extracting important information and visualizing it in a readily interpretable form. Hereby, we have provided a tutorial for multivariate classification analysis of vibrational spectroscopy data (FTIR, Raman and near-IR) highlighting a series of critical steps, such as preprocessing, data selection, feature extraction, classification and model validation. This is an essential aspect toward the construction of a practical spectrochemical analysis model for biological analysis in real-world applications, where fast, accurate and reliable classification models are fundamental.

Presentation: Understanding Chemical Characterization at the Nanoscale: Towards the development of a numerical Photo-induced Force Microscope (n-PifM), a virtual PiFM, for Image and spectroscopy calculations
Photoinduced Force Microscope (PiFM) is an incredible tool that allow us to obtaining chemical information of the specimens at the nanoscale by spectroscopy and imaging processes, with typical spatial resolutions < ~5 nm, and great Surface Sensitivity [1 – 6]. Even though the physics of these processes have already been well described [5,
6] there is a vast number of physical phenomena occurring at the tip to surface interaction junction for specific specimens. A well understanding of the physics through theoretical frame works is always beneficial and complementary to the research. The Virtual representations of Scanning Tunneling Microscopy (STM) and Frequency Modulation Atomic Force Microscopy (FM-AFM) have shown to be an amazing complement to the experimental research in the sense of understanding the origin of specific surface force fields, nanomanipulation strategies, the role of different tip geometries affecting the image due to the tip to object convolution effect, analyze set point parameters, etc. [7 – 10]. For a bimodal AM-AFM with frequency shift (df) tracking PiFM technique, lock-in amplifiers are required [2, 5]. Therefore, the creation of virtual lock-in amplifiers will be the first challenge to achieve. The main added values of such n-PiFM virtual machine can impact the optimization and experimental planning (cost reduction), enhanced understanding and interpretations of the physical phenomena happening at the tip to surface interaction, contribute to the instrument design developments and innovations, education and training purposes, understand the role of the extreme apex of the tip shape and functionalization, etc.

Paulo Sérgio De Brito Andre
Presentation: Quantum Technology: The Pathway for Intrinsic Secure Communication
Associate Professor at the Instituto Superior Técnico, Lisboa, Portugal
Senior member of the Institute of Electrical and Electronics Engineers (IEEE).
Quantum communication represent a cutting-edge technological advancement designated to revolutionize secure communications. By applying the principles of quantum mechanics, this technology offers unprecedented levels of security, addressing vulnerabilities inherent to the classical communication systems. Unlike classical encryption methods that may become vulnerable to advances in computational power and quantum computing, quantum encryption remains secure due to its reliance on the principles of quantum mechanics.
At the core of quantum communication lies the concept of quantum entanglement. Quantum entanglement involves particles becoming interlinked such that the state of one particle is strongly correlated to the state of the other, regardless of the distance separating them. This phenomenon enables the creation of highly secure communication channels.
Quantum Key Distribution (QKD), the most mature application of quantum communication, utilizes the properties of quantum mechanics to generate encryption keys that are virtually immune to eavesdropping. Any attempt to intercept the communication alters the quantum state of the particles, thereby alerting the legitimate communicators to the presence of an intruder.
This work introduces the concept of quantum communications, representing a transformative leap forward in secure communications technology. We will describe the research progress and practical implementations by our group, demonstrating its potential to become an integral component of global communication networks and ensure the highest levels of security for future communications.
Paulo Sérgio de Brito André was born in 1971. He received the Bachelor in physics engineering (1996), the Ph.D. degree in physics (2002) and the Agregação (habilitation) title in 2011, from the Universidade de Aveiro, Portugal. In 2013, he joined the Instituto Superior Técnico, University of Lisbon, as an Associate Professor, where he is lecturing courses on Telecommunications.
His current research interests include the study and simulation of photonic and optoelectronic components, optical sensors, integrated optics, photonics applications, multi-wavelength optical communications systems and passive optical networks.
Paulo André is a senior member of the Institute of Electrical and Electronics Engineers (IEEE).

City of São Pedro - SP
São Pedro is a small town in the center of the state of São Paulo. Traditionally known for its natural beauty, the quality of life is the main characteristic of the tourist resort of São Pedro. Located in the interior of São Paulo, the town of just over 38,000 people rests on the slopes of the Serra do Itaqueri mountain range. From afar, it resembles a Neapolitan crib, with its houses among trees, plantations, pastures, and two ancient towers, topped by a cross, marking the grandfatherly faith the settlers brought in the mid-19th century. In the middle of that century, many Italians left their hometown searching for good quality land with plenty of water. They wanted to set up farms and cultivate sugar cane and coffee on a large scale.
At the same time as offering a diversified hotel network for those seeking rest and tranquility, it is visited by thousands of adventurers who enjoy abseiling, jeep trails, hang-gliding and paragliding, hot air ballooning, off-roading, and waterfall bathing.
In addition to the Free Flight Ramp, the resort is known for one of its most beautiful postcards, the Parque do Cristo Aureliano Esteves, where tourists can enjoy the view from above and, on clear days, see neighboring municipalities such as Piracicaba and Rio Claro.
On Boulevard Dona Hermelinda there is an arts and crafts fair on the best local produce. As for the Producer’s Fair, in the Santa Cruz neighborhood on Saturday morning rural people sell vegetables, cheeses, and handmade sweets – and there’s also viola music.
Also in the urban area, you can go for a walk and practice some physical exercise in the Maria Angélica Manfrinato Park. In addition to the pleasant climate produced by various species of trees, there is a beautiful lake, kiosks, a mineral water fountain, a playground for children, and the store of the São Pedro Artisans Association, Art’s Trama.
In addition to the attractions in the city of São Pedro, there are many tourist attractions in nearby towns such as Águas de São Pedro and Brotas, which represent the countryside of São Paulo State.
Nearby cities
Brotas is known nationally as the Capital of Adventure, and no wonder. The city is set in a scenery of fun and nature in the interior of São Paulo. This means that it is close to major cities such as São Paulo, Campinas, Jundiaí, Ribeirão Preto, São Carlos, and Bauru. The town offers a range of extreme activities, such as rafting, boating, canyoning, zip-lining, tree climbing, cycle touring, hot-air ballooning, and much more!
However, Brotas is not just an extreme destination. Accessible to people of different ages and tastes, the city offers a variety of routes and packages. There are more than 80 gastronomic options and various tourist attractions in nature. Here, there is an option for every moment, whether you want to enjoy a weekend with the family, relax, experiment with flavors, or go on an adventure.
Brotas is a Tourist Resort, a title granted in 2014 by the São Paulo State Government. The city presents several tourist attractions, including waterfalls, parks, eco parks, and cultural attractions; waterfalls like Cachoeira 3 Quedas, Cachoeira Saltão, and Cachoeira do Astor.
Parks such as Brotas Parks Parque Jacaré, Recanto das Cachoeiras, Parque dos Saltos, Ecoparks such as Ecoparque Cassorova. and some cultural attractions like Karleen Renwick Art Gallery, Mother Church, and Largo da Santa Cruz.
Activities in the region: canoeing, walking on the singing sand, rafting, zip-lining, visiting specialized museums, seeing nature and wildlife, and visiting churches and cathedrals.
You can also visit the Casa da Cachaça, to taste and buy artisanal cachaças produced in the region.
Known for Its Medicinal Waters, This City Is an Excellent Option for Those Looking to Relax. Águas de São Pedro is Brazil’s smallest municipality, covering only 3.6 km², making it the perfect escape from the hustle and bustle of the big city. While adults enjoy some peace, children—who usually prefer more action—can have fun in the city’s charming squares, the water park pools, and even on themed train rides.
With its charm, tranquility, coziness, and warm hospitality, Águas de São Pedro is the perfect place to visit with family on weekends or during the July vacation season.
This destination is ideal for relaxation, good food, and enjoying all the benefits of the medicinal waters. To help you make the most of your trip, we’ve gathered some must-see attractions in the city.
Águas de São Pedro is considered one of the best cities to live in within the state of São Paulo. It was specifically built as a place for healing, leisure, and a high quality of life. The city shares its borders only with São Pedro and has no industries or rural areas—its economy is entirely focused on tourism.
The city was uniquely designed to preserve its miraculous waters. When Águas de São Pedro was founded, a grand hotel was inaugurated as a landmark, solidifying the city’s status as a hydro-mineral retreat for healing and relaxation. Today, the city boasts a wide variety of shops, bars, restaurants, accommodations, and attractions to welcome visitors in the best way possible. This town has a typical countryside climate— drier and mild temperatures in winter, and the summer rainy and hot. This town is very popular on weekends, holidays, and during school vacations.
The Main Tourist attractions are the Spa Thermal, Dr. Otávio Moura Andrade Square, the Municipal Fountain, and the Águas de São Pedro Staircase. You can also explore the city on the themed train ride, Biking Trails with Guide Bikers, the Almeida Salles Fountain, the Thermas Water Park, the Lady of Aparecida Chapel, and the Municipal Garden.
Beyond its medicinal waters, Águas de São Pedro also has a hidden treasure: its gastronomy. The city is home to top-quality restaurants, bars, wineries, bistros, cafés, and more, offering delicious food and exceptional service. Some recommended spots are Lá do Divino, Restaurante do Lago, and Villa Tardivelli.
