CICC ES3-2 "Optical Links" - Prof. Azita Emami

Abstract:
In this talk we will focus on design and analysis of high data rate receivers and transmitters for optical interconnects. After a description of an overall electrical-optical-electrical (EOE) link as a framework, an introduction to optical devices and their modeling for circuit designers will be presented, followed by an introduction to circuit topologies for modulator drivers, VCSEL drivers and front-end receivers. Silicon photonic devices such as micro-ring modulators, Mach Zehnder modulators (MZM), electroabsorption modulators (EAM), and waveguide photo-detectors will then be discussed. Additional topics will include the co-design of electronics and photonics, PAM4 and higher order modulation schemes, simulation and performance trade-offs, as well as equalization, bandwidth enhancement and thermal control for modulators.

Biography: Azita Emami is the Andrew and Peggy Cherng Professor of Electrical Engineering and Medical Engineering at Caltech, and a Heritage Medical Research Institute Investigator. She also serves as the Executive Officer (Department Head) for Electrical Engineering. She received her M.S. and Ph.D. degrees in Electrical Engineering from Stanford University in 1999 and 2004 respectively, and her B.S. degree from Sharif University of Technology in 1996. From 2004 to 2006 she was with IBM T. J. Watson Research Center before joining Caltech in 2007. Her current research interests include integrated circuits and systems, integrated photonics, optical interconnects, wearable and implantable devices for neural recording, neural stimulation, sensing and drug delivery. She is currently the associate editor for the IEEE Journal of Solid State Circuits (JSSC). She was the IEEE SSCS distinguished lecturer 2017-2018.

Can we achieve high sensitivity, low power optical receiver(25Gb/s) in higher nodes of cmos(180nm or 130nm)?
