Sirius, the new Brazilian Synchrotron Light Source
11:00-11:45 / Auditorium
This will a talk about Sirius, the new Brazilian Synchrotron Light Source, the largest and most complex scientific infrastructure ever built in the country and one of the first 4th-generation Synchrotron Light Sources in the World. It is planned to put Brazil in a leading position in the production of Synchrotron Light and is designed to be the brightest of all the equipment in its energy class. Synchrotron Light Sources are the most sophisticated example of an open and multidisciplinary research infrastructure and is a key tool for the resolution of issues important to the Brazilian academic and industrial communities. The versatility of a Synchrotron Light Source enables the development of research in strategic areas such as energy, food, environment, health, defense and many others. That is why this technology becomes increasingly popular around the world. It is also the reason why countries with strong, technology-based economies already either have one or more Synchrotron Light Sources, or are building them.

Photonics as a Key Enabling Technology: From Novel Light Sources to Clinical Diagnostic by Optical Imaging
09:00-09:40 / Auditorium
Photonics, the technology that deals with the generation, detection, harnessing and applications of photons, has been recognized as a key enabling technology (KET), as it is everywhere around us: from materials processing to everyday products like DVD players and mobile phones. To raise global awareness of how light-based science and technologies promote sustainable development and provide solutions to global challenges in a variety of themes, 2015 was declared as the International Year of Light by the United Nations and May 16th was declared the International Day of Light.
In this talk, I will give an introduction of some photonics developments going beyond KET to point out its economic impact. Then, I will describe how a novel type of coherent optical source, known as random laser, can be used as a platform for applications that goes from sensors to optical sources for bioimaging. To conclude, I will demonstrate how photons can be exploited for diagnostic by optical imaging in optical coherence tomography, demonstrating its ability in clinical use in dentistry and dermatology.

SHG in nanoparticles or molecules
11:30-12:10 / Auditorium
Quadratic nonlinear optical processes entailing the conversion of two photons at a fundamental energy into one photon with the sum energy are gaining a wide interest over the years. These processes obey strict parity rules in order to occur. For instance, they are forbidden in media possessing inversion symmetry like liquids. This rule can however be of a fundamental importance to investigate the special cases where inversion symmetry is broken by a small amount. Second harmonic generation, the degenerate processes of photon addition, can thus be used to investigate the bulk of liquid phases as well as liquid interfaces and smallscale aggregates, supramolecular assemblies and nanoparticles. Using second harmonic scattering, studies on the quadratic nonlinear optical response on a series of nanosystems, namely molecular aggregates and metallic nanoparticles have been performed over the last years with a special attention to the shape of the nanosystems. In particular, a competition between the shape defect contribution and the field multipole modes has been identified while the nonlinearity can be assumed to originate from the surface itself. Unfortunately, no perfect centrosymmetric shape can be achieved and it is difficult to disentangle surface defects from field multipoles. Recently, it has nevertheless been demonstrated how polarization resolved measurements could achieve this operation. To go further into this direction, we report here the second harmonic scattering response from micelles and metallic nanoparticles, both nanospheres and nanocubes. We discuss the polarization analysis and disentangle the contribution from the surface defects and the field multipoles.
Received a PhD in molecular beam spectroscopy from the University of Lyon in 1988. After a postdoctoral research at the University of Edinburgh, he moved to the Ecole polytechnique fédérale de Lausanne where he is currently studying liquid/liquid interfaces by laser spectroscopic techniques, like surface second harmonic generation.

Photonic integration, the next path for access networks.
09:00-09:40 / Auditorium
Photonics integration has been promising to be the revolution and the next step for optics.however, It has been lagging its appearance and eminence due to essentially two main lines: the constant evolution of electronics and the complexity/price of light driven components. To work around these evidences, the standard bodies have been fully engaged in opening the requirements and developing integrated visions on the network models targeting simplification and application driven solutions based on whichever optics solution best suits the objective. This has been moving the price of optics down and nowadays we can find, for example in access, optics that was costing several tens of dollars, down to a couple of dollars in a time window of less than 8 years (which is the case, for example of GPON BOSA). The revolution has not occurred yet in terms of mass deployment essentially due to the fact that there was no uniform service model set with conditions for a global usage of the technology. Platforms initiated essentially in EU arose the benefit but the model initiated has kicked off the ecosystem through open MPW (shared runs), shared PDK (platforms and models), software houses, packaging houses, and associations which manage the whole process (like Jeppix, Triplex, Lionx, ePix, etc).

Photonic Techniques for Life Sciences
09:40-10:20 / Auditorium
Light-tissue interactions are the basis for all the photonic techniques developed for Life Sciences. The possible diversity on light parameters, as wavelength, irradiance, energy, pulse width, results in the broad range of applications, from diagnostics to therapeutics. Depending on the optical properties of the target tissue, as well as the aimed tissue interaction, the light delivery and irradiation parameters can be designed. In CEPOF-USP, we have been working on the development and validation of optical techniques for medical diagnostics and treatment.
In this talk, we will discuss examples, showing the research path from the proof-of-concept up to clinical translation. Fluorescence-based detection techniques, imaging and spectroscopy, have been assembled and tested at clinical trials to evaluate their diagnostic efficacy and clinical feasibility on skin cancer. Photodynamic therapy (PDT) is a local treatment modality that is based on the use of a photosensitized molecule, light and oxygen that produces oxygen reactive species, resulting in cell death. For antimicrobial inactivation, we have been working on defining safe PDT protocols, including best photosensitizer type and delivery, and irradiation strategies customized for each infection site. For cancer treatment, we also investigate new protocols for improved response. In this case, we will discuss the strategies that we have been studying for melanoma, and present the results of a multicenter clinical study for implementing PDT for basal cell carcinoma in Brazil.

Challenges for Next Generation Coherent Transceiver ASICs
11:30-12:10 / Auditorium
The continual demand for higher internet bandwidth combined with the immergence of mega-datacenters and the explosive data rate increase promised by 5G wireless technology have created attractive market opportunities for development of high capacity optical network infrastructures. To support the highest possible data rates and distances, coherent optical transmission techniques are being developed which continue to extend the performance envelope limited only by the Shannon capacity of the transmission link. ASIC implementations of coherent optical transceivers push the limits of technology in multiple dimensions: CMOS fabrication technology, packaging technology, chip design infrastructure, modeling/simulation, CMOS analog performance, and testing, among others. Recent advances in analog-to-digital (ADC) and digital-to-analog (DAC) converter techniques have resulted in high resolution converters sampling in excess of 100Gsamples/sec allowing advanced modulation techniques to be considered. Next generation CMOS fabrication technology makes possible the digital implementation of advanced communications techniques with complexity previously thought impractical. Once in the digital domain, high-order QAM operations with dual polarization, linearization, dispersion compensation, synchronization tracking, adaptive equalization, and advanced forward error correction become feasible allowing much higher levels of performance and functionality than have ever been achieved with non-coherent transmission links. This talk will discuss the real-world challenges of designing, implementing, testing, and deploying next generation coherent transceiver ASIC products.
