Title: Scaling Capacity, Energy, and Density in Optical Communications

We discuss the scaling of optical communications from ultra-long-haul subsea cables to ultra-low power and ultra-high density co-packaged optics and show that massive spatial parallelism is the only sustainable option for the next decade and beyond.

Biography: Peter J. Winzer received his Ph.D. in electrical engineering from the Technical University of Vienna, Austria, and from 2000 through 2019 worked at Bell Labs in NJ, where performed research on fiber-optic communication systems and networks, set multiple high-speed optical transmission records, and contributed to optical communications product developments. Following his involvement in estimating the optical fiber Shannon capacity, he investigated space-division multiplexing (SDM) to scale optical transport systems. In 2020 he founded the Venture Capital backed start-up Nubis Communications. Dr. Winzer has widely published and patented and is actively involved with the IEEE and with Optica. He served as Editor-in-Chief of the Journal of Lightwave Technology (2013 to 2018), was Program Chair of ECOC 2009, and Program/General Chair of OFC 2015/2017. A Highly Cited Researcher, Bell Labs Fellow, Fellow of the IEEE and Optica, and an elected member of the US National Academy of Engineering, he received multiple recognitions for his work, including the John Tyndall Award and an honorary doctorate from the Technical University of Eindhoven.

Title: Quantum Control of Spins in Solids and Its Applications

Quantum control of systems plays an important role in modern science and technology. Spin system is an important platform for quantum control and promises various fascinating applications in quantum information science. In this talk, I would like to present our research progresses in quantum control over spins in solids, including the decoherence suppressing and high-fidelity quantum gate operations. Our experimental studies of its applications in quantum computation, quantum sensing, and fundamental physics research will also be presented.

Biography: Prof. Jiangfeng Du is a professor of University of Science and Technology of China (USTC) and the Academician of Chinese Academy of Sciences. He received his doctoral degree in USTC in 2000. Since the year 2004 he works as a professor and now he serves as vice president of USTC. Prof. Du developed a series of advanced spin quantum control methods to precisely manipulate spin quantum states as well as several kinds of advanced magnetic resonance spectrometers. Based on these, he made fruitful achievements by applying the spin quantum control technologies into information and metrology sciences. The major research results include prolonging the spin quantum coherence time by three orders against the realistic quantum noises and demonstrating the single-protein spin resonance spectroscopy under ambient conditions. Du was awarded the second prize of National Natural Science Award, The Outstanding Achievements in Natural Science by the Ministry of Education of China, The Huang Kun Award of Solid-state Physics and Semiconductor Physics from Chinese Physical Society, and The Award in Basic Science from Zhou GuangZhao Foundation.

Title: Inverse Designed, Densely Integrated Photonics

Despite a great progress in photonics over the past few decades, we are nowhere near the level of integration and complexity in photonic systems that would be comparable to those of electronic circuits, which prevents use of photonics in many applications. This lag in integration scale is in big part a result of how we traditionally design photonics: by combining building blocks from a limited library of known designs, and by manual tuning a few parameters. Unfortunately, the resulting photonic circuits are very sensitive to errors in manufacturing and to environmental instabilities, bulky, and often inefficient. We show how a departure from this old fashioned approach can lead to optimal photonic designs that are much better than state of the art on many metrics (smaller, more efficient, more robust). This departure is enabled by development of inverse design approach and computer software which designs photonic systems by searching through all possible combinations of realistic parameters and geometries. We show how this inverse design approach can enable new functionalities for photonics, including chip-to-chip on on-chip optical interconnects with error free terabit per second communication rates, which are fabricated in a commercial semiconductor foundry. Moreover, we show how photonic inverse design is crucial to implement scalable quantum photonic systems, and illustrate this with examples of inverse designed quantum photonics in diamond and silicon carbide.

Title: Prospects and Challenges for InP-based Generic PICs

Generic Integration is rapidly gaining importance. Developing and fabricating PICs from a limited set of Basic Building Blocks in a standardized and qualified integration process leads to a huge reduction of the development costs. This is well known in micro-electronics. Also in Integrated Photonics generic foundry-based integration processes are being developed, both in Silicon and Indium Phosphide. However, the markets for PICs are smaller by several orders than their micro-electronic counterparts, and this makes investors hesitant to provide the capital required to make photonic foundry processes and the corresponding design, test and packaging infrastructure sufficiently qualified. Instead, they tend to focus on business development to increase the market, which is difficult, however, when there are no sufficiently qualified processes.
In this presentation an overview will be given of the present status and prospects of InP-based generic integration and the challenges that have to be overcome to turn the present integration environment into a well-qualified foundry infrastructure.

Biography: Meint K. Smit started research in photonic integration in 1981. He invented the Arrayed Waveguide Grating (LEOS Technical Achievement 1997) and was closely involved in the introduction of MMI-couplers, key components in Photonic ICs. In 2000 he became the leader of the Photonic Integration group at the COBRA Research Institute of TU Eindhoven. He is the founder of the JePPIX platform, the Joint European Platform for Photonic Integration of Components and Circuits and he was strongly involved in the development of the InP-based photonic foundry system in Europe. Meint Smit is an IEEE Fellow. In 2012 he received an ERC Advanced Grant, in 2016 the Rank Prize for Optoelectronics and in 2021 the Tyndall Award.
Biography: Kevin A. Williams leads the Photonic Integration research group at Eindhoven University of Technology (TU/e). His key fields of expertise include photonic integrated circuits, semiconductor lasers and their application in communications and sensing. The research group explores the scaling properties of photonic circuits, enabling faster and more energy-efficient components and circuits. The group builds on its know-how in active-passive monolithic and heterogeneous InP integration, creating circuits with lasers, amplifiers, energy-efficient quantum well modulators, detectors, power splitters, filters and more all on the same chip. Kevin is coordinator for the JePPIX Pilot Line, which is enabling the upscaling of indium phosphide photonic integrated circuit production using the pure-play foundry model.
