[AP483] Energy Efficient, Multi-Terabit Photonic Connectivity for Disaggregated Computing

Abstract / Description: 

High performance data centers are increasingly bottlenecked by the energy and communications costs of interconnection networks. Integrated silicon photonics with dense wavelength-division multiplexing offer the opportunity of optical connectivity that directly delivers high off-chip communication bandwidth densities with low power consumption. We introduce the concept of embedded photonics for deeply disaggregated architectures. Beyond alleviating the bandwidth/energy bottlenecks, the new architectural approach enables flexible connectivity tailored for specific applications.


Spring 2021 speakers organized by Prof. David A.B. Miller

Bio: Keren Bergman is the Charles Batchelor Professor of Electrical Engineering at Columbia University, where she also serves as the Faculty Director of the Columbia Nano Initiative. Prof. Bergman received the B.S. from Bucknell University in 1988, and the M.S. in 1991 and Ph.D. in 1994 from MIT, all in Electrical Engineering. At Columbia, Bergman leads the Lightwave Research Laboratory encompassing multiple cross-disciplinary programs at the intersection of computing and photonics. Bergman serves on the Leadership Council of the American Institute of Manufacturing (AIM) Photonics, leading projects that support the institute's silicon photonics manufacturing capabilities. She is the recipient of the 2016 IEEE Photonics Engineering Award and is a Fellow of the Optical Society of America (OSA) and IEEE.
