The Revolution of Silicon Photonics

09:05—12:30  /  Auditorium

In the past decade the photonic community witnessed a complete transformation of optics. We went from being able to miniaturize a handful of devices to being able to define and control the flow of light using thousands of monolithically integrated optical components – all on a silicon chip. The main drive for silicon photonics is the ability to transmit and manipulate ultra high bandwidth with low power dissipation. Today there are hundreds of products being developed and commercialized towards this goal. The field of silicon photonics is rapidly evolving and is now enabling completely new applications, ranging from Lidar to biomedical devices. This is partly due to the development of novel chip-scale technologies, novel devices and novel materials compatible with silicon photonics. Many of these technologies and devices can manipulate light across the whole VIS, IR and the Mid IR spectrum. I will discuss these emerging applications, as well as the advancement brought by these novel devices and materials. The key challenges of the field relate to the scalability of the systems in bandwidth, size and power. Some of these challenges are fundamental and require innovations that break traditional tradeoffs. Novel approaches for switching, modulating and amplifying light have emerged that can open the door to applications that rely on such scalable systems. I will describe the challenges of the field and some of the recent innovations that can potentially address these challenges.

OSA, SPIE, IPS Student Chapters: Connecting students with light

09:05—12:30  /  Auditorium

Student Chapters are student-managed affiliations of consolidated scientific societies. Usually, these are formed by students in their research centers, and establishe a mutual gain relationship between the represented societies, the students and their centers. Organizing academic and outreach events, funding ideas and integrating students are some of the benefits provide by scientific societies to Student Chapters. Besides, Student Chapters aim to spread the ideals of these scientific societies for the community it covers. As a final result, there is a strengthening of the scientific network. In this Plenary, members from different Brazilian Student Chapters on Optics & Photonics (OSA, SPIE, IEEE) will present the Chapters activities, and share their experiences with the audience. We hope to encourage the founding of new Student Chapters and to strengthen our Optics & Photonics community.

Cold atoms in the degenerated quantum regime: turbulence and systems out-of-equilibrium

09:05—12:30  /  Auditorium

Quantum many-body systems out of equilibrium pose several problems which are long-standing in physics. Thanks to the possibilities to investigate such systems with cold trapped atoms, a tremendous advance in those questions are being addressed.

Next generation coherent optical pluggable modules

09:00—12:30  /  Auditorium

In this talk, we review the coherent optical transceiver evolution since the early 100 Gb/s to current 400 Gb/s systems. The talk will focus on the system aspects and technological challenges considering the massive adoption of pluggable optics for different applications. In the final part of the presentation, we address one of the most relevant topic in current coherent systems, which is how to optimize power dissipation and still keep up with a reasonable system performance for short-reach data center interconnection and WDM metro applications.

Rogue Photonics

09:00—12:30  /  Auditorium

Random events in nature are of great scientific interest as they influence weather, spread of disease, the formation of rogue waves, glassy magnetic behavior, instabilities, turbulence, symmetry breaking, initiate chaos, and lead to Anderson localization in the solid state. These important phenomena have recently found a platform: photonics - to model, further understand and shed light on these various observations within the convenience of a laser laboratory. The link between chaos and lasing has thus, become a significant field of study. Random phenomenon has been shown to occur in Rayleigh, Brillouin and Raman scattering. This presentation charts the very rich area of research showing how scattering of light has been used to easily generate photonics analogues of these events. The Rogue, a random optical fibre grating written by UV radiation or ultrafast lasers, leads to a new type of localization of light, and how the removal of randomness results in high quality, well behaved, state-of-the-art lasers.

Coherent Transmitters: what, how and when?

09:00—12:30  /  Auditorium

As capacity demands continues to increase, and standard single mode fibres still prevails, techniques to maximise the spectral efficiency of the fibre available bandwidth are now moving from research to implementation. While DSP and higher order modulation formats are becoming widely available commercially, in particular for 400G+ approaches, Tb/s capacities are likely to be achieved with multi-carrier schemes. In this plenary talk, we will review the need and what coherent transmitters are, show potential solutions and how to overcome their challenges , and discuss when this technology will be potentially ready.

2D materials: from optical characterization to photonic application

09:00—12:30  /  Auditorium

From early years, optical methods, such as Raman, photoluminescence and absorption spectroscopies, have been of utmost importance for the characterization 2D materials. Among other characteristics, these methods allow for the determination of the 2D crystals’ number of layers, doping levels and defect densities. More recently, the incorporation of 2D materials on optical substrates and waveguides have allowed for a wide variety advanced photonic devices to be designed for prospective applications ranging from molecular sensing to optical communications and infrared/terahertz technology. For being flexible and not making out-of-plane chemical bonds, such an incorporation can easily be accomplished, while the increasing variety of 2D materials available allows for different optical properties to be obtained from the resulting device architecture. In this talk, I will review the recent activity carried out at MackGraphe towards the optical characterization and photonic application of 2D materials. I will show that the polarized Raman spectrum of orthorhombic lamellar materials, such as black phosphorus and germanium sulfide, incorporates valuable information about their edge structures. Also, nonlinear optical frequency conversion will be shown as an example of the ability to change the properties of light by exploiting electronic and excitonic processes in 2D materials. The incorporation of graphene oxide as well as nanocomposite materials onto the internal walls of microcapillaries in optical fibers will be described as means to develop devices for molecular sensing via surface enhanced Raman spectroscopy (SERS), as well as to generate ultrashort pulses in fiber lasers via mode locking.

Nonlinear wave-mixing and photonic phase transitions in Random Lasers

09:00—12:30  /  Auditorium

Random Lasers (RLs) are excellent platforms to study disordered photonics and to understand the behavior of a large variety of complex systems. The RL emission is obtained from disordered materials instead of ordered systems inside optical cavities, as in conventional laser. The feedback for laser action is provided by multiple scattering of light in the gain medium. No optical cavity is used but the RLs present resonance frequency modes due to constructive optical interference of scattered light inside the gain medium. In this presentation I will review recent advances in the RL research with examples for one-, two-, and three-dimensional systems operating in pulsed and continuous-wave regimes. In particular I will focus on nonlinear wave-mixing processes among the various lasing modes that contribute to photonic phase transitions characterized by strong output intensity fluctuations. Analogies to the statistical mechanics of complex systems emerge from the analysis of the RLs behavior. The characterization of Lévy distributions for the intensity fluctuations probability distributions, the demonstration of replica-symmetry- breaking which is the most fascinating and fundamental concept of spin-glass theory, and extreme intensity events with power law assymptotic tail are examples of remarkable phenomena in RLs that will be discussed.
