Special EECS Seminar: Electronic and Photonic 1+1=3

Seminar: Departmental | March 21 | 3:30-4:30 p.m. | Cory Hall, Hogan Room (521)


Firooz Aflatouni, Postdoctoral Associate, California Institute of Technology

Electrical Engineering and Computer Sciences (EECS)


When we look at the long-term future of silicon electronics, it is apparent that the field will become increasingly inter-disciplinary. Despite great near/mid term research opportunities, it is necessary for the field to bridge the gap with other streams of science and engineering to grow further. I envision that the next several years will witness a great synergy between the fields of silicon electronics and photonic integrated circuits. It is not difficult to imagine that integrated electronic-photonic co-design will profoundly impact both fields resulting in advances in several areas such as communications, signal processing, imaging, and sensing.

Examples of Electronic-Photonic Co-Design may be categorized into two groups: (a) electronic assisted photonics, where analog, RF, mm-wave, and THz circuits 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, mm-wave, and THz systems.

In this talk, as an example of electronic assisted photonics, I will present my work on RF assisted phase control of semiconductor lasers and will discuss its advantages and limitations. I will also present my work on integrated opto-electronic oscillators as an example of photonic assisted electronics.


Bio: Firooz Aflatouni received the M.S. and Ph.D. degrees in electrical engineering from the University of Southern California, Los Angeles, in 2005 and 2011, respectively. He is currently a Post-doctoral Associate in the department of electrical engineering at the California Institute of Technology, Pasadena, CA. His research interests include RF-inspired photonics and low power RF, mm-wave, and THz integrated circuits. In 1999, he co-founded Pardis Bargh Company, where he was involved in the design of inclined-orbit satellite tracking systems. From 2004 to 2006, he was a Design Engineer with MediaWorks Integrated Circuits Inc., Irvine, CA. He was the recipient of the 2011 USC department of electrical engineering best Ph.D. thesis 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.
