Integrated photonics is poised to revolutionize inter- and intra-data center communications since internet traffic continues to increase exponentially making it difficult and costly for existing switching and interconnects in data centers to cope with the fast-growing bandwidth requirement. Silicon photonics is able to contribute data centers in terms of the lower cost, higher bandwidth, and lower power consumption. As many fundamental components including the power-efficient modulators, integrated photonics is believed to have reached the tipping point with a surging global market. Besides the optical interconnects, integrated photonics also shows the promise in abundant applications, ranging from high performance computing and autonomous cars, to biomedical sensing and even aerospace applications.
In this talk, an overview of the silicon photonics as well as a potential trend for 2020 and beyond will be provided. First, the recent development of optical components including passive and active modules as well as optical circuits in silicon photonics will be presented. Second, as Moore’s law has been approaching the physical limitation, photonics-based high-performance computing is envisioned as a potential answer to the continuation of Moore’s law. We propose and experimentally demonstrate a new photonics-assisted full adder which is capable of operating at a higher frequency than electrical counterparts while consuming less power. This paves the way to the future integrated high-speed and power-efficient optical computing. Sensing related applications will also be addressed in the presentation. Finally, the main challenges that require technical breakthroughs for the upcoming years will be discussed.
Ray T. Chen at UT Austin has reported its research findings in more than 970 publications, including over 100 invited papers and 74 patents. He has chaired or been a program-committee member for more than 120 domestic and international conferences organized by IEEE, SPIE (The International Society of Optical Engineering), OSA, and PSC. He has served as an editor, co-editor or coauthor for over twenty books. Chen has also served as a consultant for various federal agencies and private companies and delivered numerous invited talks to professional societies. Chen is a Fellow of IEEE, OSA, and SPIE. He was the recipient of the 1987 UC Regent’s Dissertation Fellowship and the 1999 UT Engineering Foundation Faculty Award, for his contributions in research, teaching and services. He received the honorary citizenship award in 2003 from the Austin city council for his contribution in community service. He was also the recipient of the 2008 IEEE Teaching Award, and the 2010 IEEE HKN Loudest Professor Award. 2013 NASA Certified Technical Achievement Award for contribution on moon surveillance conformable phased array antenna. During his undergraduate years at the National Tsing Hua University he led the 1979 university debate team to the Championship of the Taiwan College-Cup Debate Contest.
Chen served as the CTO, Founder, and Chairman of the Board of Radiant Research, Inc. from 2000 to 2001, where he raised 18 million dollars A-Round funding to commercialize polymer-based photonic devices involving over twenty patents, which were acquired by Finisar in 2002, a publicly traded company in the Silicon Valley (NASDAQ:FNSR). He also serves as the founder and Chairman of the Board of Omega Optics Inc. since its initiation in 2001. Omega Optics has received over five million dollars in research funding. His research work has been awarded over 135 research grants and contracts from such sponsors as Army, Navy, Air Force, DARPA, MDA, NSA, NSF, DOE, EPA, NIST, NIH, NASA, the State of Texas, and private industry. The research topics are focused on four main subjects: (1) Nano-photonic passive and active devices for bio- and EM-wave sensing and interconnect applications, (2) Thin film guided-wave optical interconnection and packaging for 2D and 3D laser beam routing and steering, (3) True time delay (TTD) wide band phased array antenna (PAA), and (4). 3D printed micro-electronics and photonics. Experiences garnered through these programs are pivotal elements for his research and further commercialization. Chen has supervised over 30 postdocs and graduated 51 PhD students from his research group at UT Austin. Many of them are currently professors in the major research universities in USA and abroad.
