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.

Presentation: Waveguides with different architectures based on GeO2 and TeO2 and decorated with Au nanoparticles 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 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 decorated with Au nanoparticles, deposited by the sputtering technique, 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 favour 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

Claire Cisowski
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.
Giorgio Senesi
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.

Hilde Harb Buzza
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.
Paulo Sérgio De Brito André
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.

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.
