Optical Devices and Materials for Solar Energy and Solid-state Lighting

Optical Devices and Materials for Solar Energy and Solid-state Lighting

29 July - 01 August 2019
Hyatt Regency San Francisco Airport, Burlingame, California United States

The meeting covers the latest developments in nanophotonics and advanced materials for the next generation of photovoltaic (PV) solar cells and light emitting diodes (LEDs). This includes all aspects of novel optical materials, nanostructures, and devices, ranging from surface coatings, textures and diffraction gratings to topics such as plasmonics, nanowires, quantum dots for application in solar cells and LEDs - both conventional and emerging types alike. It also explores the range of optical elements for collecting, guiding, concentrating, coupling, trapping, transforming and absorbing sunlight – particularly for concentrating solar power (CSP). As optical components typically constitute the largest fraction of cost of such systems, the scope includes research devoted to improving all optical aspects of solar systems to enhance the performance, such as reducing levelized costs and maximizing long-term reliability.

Attendees will be presented with overarching topics such as the techno-economic analysis of the impact of optics on solar and solid-state lighting systems. The aim is to bring together solar energy researchers with LED researchers and connect them with the broader global optical research community to identify and promote synergies.

Plenary Session

Keren Bergman

Empowering Flexible and Scalable High Performance Architectures with Embedded Photonics

The explosive growth in data analytics applications that rely on machine and deep learning techniques are seismically changing the landscape of high performance architectures. Driven by these applications, systems' performance is increasingly bottlenecked by the energy and communications costs of interconnecting the numerous heterogeneous compute and memory resources. Recent advances in integrated silicon photonics offer the opportunity of embedding optical connectivity that directly delivers high off-chip communication bandwidth densities with low power consumption. This talk will review these advances and introduce the concept of embedded photonics for addressing data-movement challenges in high-performance systems. Beyond alleviating the bandwidth/energy bottlenecks, embedded photonics can enable new disaggregated architectures that leverage the distance independence of optical transmission. We will discuss how the envisioned modular system interconnected by a unified photonic fabric can be flexibly composed to create custom architectures tailored for specific applications.

Special Sessions

Symposium: A Light in Digital Darkness: Optical Wireless Communications to Connect the Unconnected

Tuesday, 30 July 2019, 19:00 - 21:00
Grand Peninsula EF

The role of Internet and Communication Technology (ICT) in bringing about a revolution in almost all aspects of human life needs no introduction. It is indeed a well-known fact that the transmission of information at a rapid pace has transformed all spheres of human life such as education, health, and economy to name a few. Despite this tremendous advantages that come with ICT, it is a fact that almost 4 billion people in the world are still “unconnected or under-connected” or suffer from the “digital/connectivity divide,” a term coined in order to emphasize the lack of communications infrastructure in many parts of the world. In this symposium, top experts will offer ways to provide high speed connectivity in rural areas along with efficient and cost-effective backhauling methods for rural traffic. In particular, Free Space Optical Communications (FSOC)-based solutions for both: (i) integrated satellite-airborne-ground networks providing global coverage and connectivity and (ii) terrestrial mesh/multi-hop directive networks connecting far-flung regions of the state will be discussed and debated.

Quantum Technologies Symposium

Wednesday, 31 July 2019, 08:00 - 16:00
Grand Peninsula EF

Quantum technology is maturing, with fields like quantum computing and quantum key distribution approaching commercialization. First quantum computers are being made available to the general public and quantum key distribution systems are being deployed. Quantum computers promise a significant increase in the speed at which complex mathematical problems can be solved. As a result, numerous classical encryption algorithms used in telecommunication are in danger of being easily broken. Next to “post-quantum cryptography”, quantum key distribution (QKD) has been proposed as a solution to ensure secure communication in the era of quantum computing. Most systems shown so far are laboratory prototypes to prove the general concept and to build first QKD links, whose stringent requirements for a successful deployment in commercial networks are yet to be addressed. Transforming QKD into a widely deployable technology entails major challenges that require close interaction between the quantum and the telecommunications community. The long history and deep knowledge of classical communication principles from the latter group can support the commercialization of the theoretical findings of the former, leading to more elegant and simpler solutions for future quantum systems.

This symposium will provide an introduction to quantum technologies and a platform to improve collaboration and understanding between the classical communication community and the quantum community. Quantum researchers, classical communication researchers and telecome operators will provide  a broad range of insights.
