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.
