The Integration of Silicon Photonics & VLSI Electronics for Computing Systems Intra-connect
Thursday, Feb. 12, 2009
4:15pm, Ginzton Building, AP 200
Refreshments at 4:00pm
Abstract: This talk will briefly review the progress and challenges in scaling computing systems and meeting computing systems interconnect needs. We will discuss the potential benefits and challenges for achieving extremely short-reach, low-energy optical-interconnects via the native integration of silicon photonics components with VLSI electronics and introduce the "macrochip" – a collection of contiguous silicon chips enabled by optical proximity communication.
About our speaker: Ashok V. Krishnamoorthy received his Ph.D under Prof. Sadik Esener in Applied Physics from UCSD with the thesis topic of the first free-space optically-interconnected CMOS neural network. After working on the research faculty of UCSD, he joined the Advanced Photonics Research Department of Bell Labs, led by Dr. David Miller to investigate methods of integrating optical devices including photodetectors, multiple quantum well modulators, and later VCSELs, to Silicon VLSI circuits. After joining Lucent New Ventures in 1999, he moved on to become President and CEO of AraLight as part of a Lucent Bell Labs spinout. After successfully launching the optical interconnect product and completing several customer trials, he sold the technology in 2003. He then joined SUN Microsystems' Physical Sciences Center and was soon named a Distinguished Engineer by Sun Microsystems and is currently their principal investigator for advanced optical interconnect development and silicon photonics.
Ashok and his colleagues have achieved several technical milestones related to applied photonics technology. He also played the lead role in several optoelectronics industry milestones including: the first CMOS-based opto-electronic foundry service to disseminate Optoelectronic-VLSI technology to R&D institutions around the world; the first demonstrated parallel optics transmitter/receiver product using VCSELs with over 100Gb/s throughput, and the first 300meter opto-electronic backplane application demonstration using VCSELs integrated with switches.
Dr. Krishnamoorthy has served as member and chair of several conference program committees for the Optical Society of America, the IEEE Laser and Electro-Optics Society (LEOS), and the IEEE Computer Society. He also serves on the technical advisory board for several optical technology start-ups and venture funds. He is an honorary member of Tau Beta Pi, Sigma Xi, and Eta Kappa Nu. For his contributions to optoelectronics, the Eta Kappa Nu society named him an Outstanding Young Electrical Engineer in 1999. He was presented the IEEE LEOS Distinguished Lecturer award for 2002 and 2003. For his technical inventions, he has been granted 40 patents. He has co-authored 150 technical publications in optoelectronics, 6 book chapters and contributed over 60 invited talks at international conferences. He was awarded the 2004 International Prize in Optics by the ICO for his contributions to optical interconnects and received the 2006 Chairman's award for Innovation by Sun Microsystems for his work on silicon photonic systems. He has also won several team awards, including Computerworld's Horizon award for innovation.
