Masayuki Itoh (M'01) was born in Tokyo, Japan, in 1963. He received the B.S. and the M.S. degrees in solid-state physics from Hokkaido University, Sapporo, Japan, in 1987 and Tohoku University, Sendai, Japan, in 1989, respectively. Since 1989, he has worked at Nippon Telegraph and Telephone Co. (NTT), Kanagawa, Japan, as a research scientist in the Basic Research Laboratories and the Photonics Laboratories. His major works have concentrated on physics and nanofabrication of semiconductors for high-quality opt-electronic devices. Since 1995, he has been engaged in the research on integrated devices using lasers, semiconductor optical amplifiers, and silica-based planar lightwave circuits. His current interests are in mesoscopic physics, nanofabrication, and opt-electronics. Mr. Itoh is a member of the Japanese Society of Applied Physics (JSAP) and the IEEE Lasers and Electro-Optics Society (LEOS).
