Photonic Networks and Devices (NETWORKS)

25 July 2022 – 28 July 2022

NETWORKS brings together researchers and engineers from various communities that intersect in today's applications that require photonic networks. The new applications and network architectures will both drive and utilize innovations in optical transmission and photonic devices. Growing demands for bandwidth, flexibility, programmability, resilience, security, low cost, high integration, high functionality, low power consumption, and small footprint require novel solutions in photonic networks and devices. New management paradigms in the framework of software-defined networking are needed for efficient and dynamic programmability of virtualized network resources.  
NETWORKS focuses on fostering research that supports the future scaling and performance requirements of emerging applications, including spectrally and spatially multiplexed systems, data centers and data-center interconnections, cloud infrastructure, high-performance computing, and content delivery.

New Materials and Structures for Photodetection

Some compound semiconductors such as GaAs and InGaAsP exhibit a high absorption coefficient in the photon energy of interest for solar energy conversion. The direct bandgap associated with strong tuneability of emission wavelength, renders compound semiocnductors the material of choice for optoelectronic applications. Their commercial potential in high production volume applications is reduced due to the scarcity (and thus high cost) of group III elements such as In and Ga. In this talk we present approaches to render the use this kind of materials sustainable: a strong reduction in material use through nanostructures and the replacement of III-V compounds by GeSn or Zn3P2 that contain much more abundant elements. We find nanostructures also provide a path to increase light collection and provide some instructions for optimal devices[1,2]. We explain how these materials can be fabricated with high crystal quality, opening the path for the creation of alternative and sustainable compound semiconductor solar cells [3-5].

Progress on Optical Single-sideband Transmission

There are only two modulation schemes which have been commercially deployed in fiber optical communications, namely the intensity modulation (IM) and the dual-polarization Quadrature Amplitude Modulation (QAM) schemes. These two modulation schemes, however, are very different in term of spectral efficiency, implementation’s complexity, transmission performance and reliability. Compared to the IM scheme, single sideband (SSB) modulation scheme can offer enhanced transmission performance and spectral efficiency. While SSB scheme has lower spectral efficiency than dual-polarization QAM scheme, it can provide additional functionalities, lower complexity and higher reliability. Because of these unique features, SSB modulation can be a suitable modulation format for several emerging applications such as dispersion tolerant DWDM regional and access networks, data center interconnect, optical network monitoring and 5G mobile fronthaul. In this talk, we will review the recent progress of optical SSB modulation for these applications and discuss its potential for commercialization in the near future.

Light Trapping in Perspective; Not Just for Current, it Boosts Voltage Too

Almost all commercial solar panels use Light Trapping which increases the internal optical path length by 4(n squared), increasing the current, where n is refractive index.  In spite of numerous ingenious attempts, that classical enhancement factor has not been superseded.  It is sometimes over-looked that operating point Voltage also increases, by (kT/q)ln{4(n squared)}~100mVolts.

About the Speaker

Eli Yablonovitch is Director of the NSF Center for Energy Efficient Electronics Science (E3S), a multi-University Center headquartered at Berkeley. Yablonovitch introduced the idea that strained semiconductor lasers could have superior performance due to reduced effective mass (holes). With almost every human interaction with the internet, optical telecommunication occurs by strained semiconductor lasers. He is regarded as a Father of the Photonic BandGap concept, and he coined the term "Photonic Crystal". The geometrical structure of the first experimentally realized Photonic bandgap, is sometimes called “Yablonovite”. He was elected to NAE, NAS, NAI, AmAcArSci, and as Foreign Member, UK Royal


Special Events

Symposium: Forty Years of Light Management

Forty years ago, in December 1981, Eli Yablonovitch submitted his seminal paper on “Statistical Ray Optics,” which was one of the first papers investigating light management for solar cells from a fundamental physics perspective.

Light management has mainly been performed with antireflective coatings and textures, which enhance the average light path and hence, absorption in the solar cells. In the last twenty years highly innovative concepts were also investigated, such as (quasi)periodic structures, plasmonic nanostructures, Bragg reflectors, and photonic up- and downconversion. On the other hand, state-of-the-art silicon solar cells have almost perfect light trapping with external quantum efficiencies close to 100% for a broad wavelength range using only conventional light trapping techniques.

With this symposium, we aim to bring together leading experts in the field representing all the light management concepts investigated during the past forty years. We will critically review different light trapping techniques developed in the past decades and discuss, how the field may and should develop further.

Bioinspired Optics: From Fundamental Biology to Tools and Applications

NOMA Symposium outline:

The thematic focus of this symposium will be on the interdisciplinary area of bioinspired optics: specifically, understanding nature’s optical design principles and leveraging them for the development of novel optical tools. The talks will cover various approaches in biomolecular engineering and nanofabrication methodologies, which strive to emulate some of the unique light-manipulating capabilities of living systems, as well as the implementation of new optical characterization strategies. The symposium aims to encourage interdisciplinary discussion, with the simultaneous hope of identifying new research opportunities in bioinspired optics and photonics, advancing fundamental biological understanding, and accelerating next-generation optical tool development. Through our cross-disciplinary focus, we are striving to cultivate a cohesive and inclusive community of scientists at all career stages and from across all demographic groups.
