Title: Nonlinear effects mitigation on WDM signals enabled by optical phase conjugation

Abstract:

A high performance photonic functional device is the key to realization of large capacity, energy efficient, and low-cost networks. In this seminar, wavelength selective switches (WSS) using silica and silicon waveguides, a small-sized optical switch using phase-change material, and optical devices for T-band (1000 -1260 nm) are presented.

Prof. Hiroyuki Tsuda

Bio: 

Hiroyuki Tsuda received the B. S. degree from Waseda University, Japan, in 1985, the M. E. and Ph. D. degrees from Tokyo Institute of Technology, Japan, in 1987 and 1998, respectively. In 1987, he joined NTT Opto-electronics Laboratories, where he was initially engaged in the research on nonlinear optical devices. In 1994, he was engaged in the development of long-haul 10 Gbit/s transmission systems. In 1996, he was engaged in the research on the optical signal processing using optical waveguide devices. Since 2000, he has been at the Department of Electronics and Electrical Engineering, Keio University, where he is now a professor. His research subjects are optical devices using silica and silicon waveguides for an optical communication system, and an optical sensing system.
