"Si Electronic-Photonic Integrated Circuits Realized with Standard Si Technology"

Woo-Young Choi , Professor, Yonsei University, Korea

March 9th (Friday), 1:00pm
Harold Frank Hall (HFH), Room 4164

There are growing interests in Si Photonics and, in particular, Si Electronic-Photonic Integrated Circuits (EPIC) in which photonic devices are integrated with Si electronics on a single Si platform. EPICs for high-performance optical transceivers have been already demonstrated and their implementations for various other applications are expected. At Yonsei University, we have pursued EPICs based on standard Si fabrication technology. We developed Si Avalanche Photodetectors(APDs) for 850nm applications. By integrating Si APDs with powerful Si electronics, we successfully realized high-performance Si optical receivers as well as photonic-wireless interface ICs for 60GHz applications. These new EPICs will be introduced in the seminar.

About Woo-Young Choi :

Woo-Young Choi received his B.S., M.S., and Ph.D. degrees in electrical engineering and computer science from the Massachusetts Institute of Technology (MIT), USA, in 1986, 1988, and 1994, respectively. For his doctoral thesis, he investigated molecular-beam epitaxy (MBE) grown InGaAlAs laser diodes. From 1994 to 1995, he was a Post-Doctoral Research Fellow at NTT Opto-Electronics Laboratories, Japan, where he worked on femto-second all-optical switching devices. In 1995, he joined the department of electrical and electronic engineering, Yonsei University, Korea, where he is currently a professor. At Yonsei University, he has pursued various research topics that can be broadly categorized as high-speed circuits and systems. Presently, his research interests are high-performance Si Electronic-Photonic integrated circuits.
