Title: Comb and Hybrid Laser Driven WDM Silicon Photonic Interconnects for Exascale and High Performance Computing Applications
Speaker: Ashkan Seyedi
Affiliation: Research Scientist, HPE
Day: Friday, November 17, 2017
Time: 3:00 pm - 4:00 pm
Location: LSC 310

Abstract: This talk outlines the work done at Hewlett Packard Enterprise (HPE) on photonic interconnects using key components such as micro-ring modulators, avalanche photodiodes, and quantum dot comb and hybrid ring lasers to power exascale and high-performance applications. A brief overview of individual device performance is followed by a system-scale analysis of power consumption, optical crosstalk, and overall fiber bandwidth that is achievable by the various proposed architectures. The most recent results on CMOS/Photonic chip flip-chip packaging will also be reviewed as a means to enable future architectures using these various photonic components.

Bio: Ashkan received a dual Bachelor's in Electrical and Computer Engineering from the University of Missouri-Columbia and a Ph.D. from University of Southern California working on photonic crystal devices, high-speed nanowire photodetectors, efficient white LEDs and solar cells. While at Hewlett Packard Enterprise as a research scientist, he has been working on developing high-bandwidth, efficient optical interconnects for exascale and high performance computing applications.
