Integrated Systems Seminar Series

Speaker: Firooz Aflatouni, University of Southern California

Talk Title: Electronic-Photonic Co-Design: RF Assisted

Abstract: The relative phase control of semiconductor lasers is the basis for many applications including RF assisted coherent power combining of semiconductor lasers and laser beamforming.
Also, absolute phase control of semiconductor laser (where the laser phase noise is reduced) is highly desired in many applications such as coherent optical communication (long-haul or chip-to-chip), interferometric sensing, LIDAR, and mmwave
and THz signal generations.
These are examples of Electronic-Photonic Co-Design which can be categorized into two main aspects: (a) RF Assisted Photonics where RF and mm-wave circuits and techniques are employed to improve the performance of photonic systems, and (b) Photonic Assisted Electronics where photonic systems and devices are used to improve the performance of the RF and mm-wave systems.
In this talk, I will present my work on RF assisted phase control of semiconductor lasers in both relative sense (coherent power combining) and absolute sense (laser phase noise reduction) and will discuss its advantages and limitations.

Biography: Biography: Firooz Aflatouni received the B.S. and M.S. degrees in electrical engineering from the K.N.T. University of Technology, Tehran, Iran, and the University of Southern California (USC), Los Angeles, in 1998 and 2005, respectively. He is currently working towards the Ph.D. degree at USC. In 1999, he co-founded Pardis Bargh Company, where he was involved in the designing of inclined- orbit satellite tracking systems.
From 2004 to 2006, he was a Design Engineer with MediaWorks Integrated Circuits Inc., Irvine, CA. He is currently a research assistant in the Electrical Engineering Department at USC. His research interests include RF-inspired photonics and low power mm-wave and RF integrated circuits.
He was the recipient of the 2011 USC department of electrical engineering best research presentation award, 2010 USC Ming Hsieh top 5 PhD student scholarship, 2010 NASA Tech Award for his work on development of a Ka-Band SiGe receiver front-end MMIC for space transponder applications, and the best B.S. thesis award for design and implementation of a non-geostationary satellite tracking system. He is the Silver medal winner of the nationwide Mathematics Olympiad in 1993.
