报告摘要

This talk first reviews key issues of photonic devices for future systems and then discusses recent developments using semiconductor nanostructures with a particular focus on ultrafast switching devices based on quantum dot (QD) materials. They include QD-based semiconductor optical amplifiers (SOAs) exhibiting polarization-insensitive operation at >40 Gb/s and novel QD-based vertical cavity structure photonic switches showing ultrafast, power-efficient all-optical switching capability. Nanostructure-based photonic devices are summarized and discussed for future applications.

 

报告人简介: Osamu Wada received the BE degree in 1969 at Himeji Institute of Technology and ME degree in 1971 at Kobe University, both in Japan and the Ph.D. degree in 1980 at the University of Sheffield, UK. He was with Fujitsu Laboratories Ltd., Atsugi, Japan in 1971-1996, being engaged in research on III-V semiconductor materials and devices such as LEDs, lasers, photodiodes, and optoelectronic integrated circuits (OEICs) for telecom and interconnect systems. In 1996-2001, he worked for the development of femtosecond ultrafast all-optical switches at FESTA Labs., Tsukuba, Japan for a NEDO/METI project. During 2001-2010, he was a Professor at Graduate School of Engineering, Kobe University, Kobe, Japan and headed a group on nanostructure materials and ultrafast photonic devices. He is a Fellow of IEEE, OSA, IEICE, and JSAP. He is currently Director of Japan Society for the Promotion of Science (JSPS) Beijing Office.
