Si photonics technology promises realization of high-performance photonic devices on Si wafers with Si processing technology. This will greatly enhance mass production capabilities of photonic devices and their cost effectiveness. Furthermore, it is now possible to realize both photonic and electronic devices on the same Si wafer. Such Electronic-Photonic Integrated Circuits (EPICs) are expected to solve the interconnect bottleneck problem from which many modern electronic systems suffer. In this presentation, I will first give a brief introduction to Si photonics, emphasizing why photonics is needed for Si systems and how it can be implemented. In addition, I will present recent research results at Yonsei University where we have developed Si avalanche photodetectors based on standard Si fabrication technology and integrated them with high-speed Si circuits for realization of high-performance Si EPIC receivers for wireline and wireless applications.
Prof. 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. For his doctoral thesis, he investigated InGaAlAs laser diodes fabricated by molecular beam epitaxy for fiber-optic applications. From 1994 to 1995, he worked at NTT Opto-Electronics Laboratories in Japan as a research fellow and investigated femto-second all-optical switching devices for ultra-fast optical communication applications. In 1995, he joined the department of electrical and electronic engineering in 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 interconnect technology. Specifically, he has worked on high-speed wireline and wireless Si circuits, high-speed optoelectronic devices, and microwave photonic devices and systems. He has substantial research experiences in both high-speed electronics and photonics and, presently, he is using these for realization of high-performance Si Electronic-Photonic Integrated Circuits.
