"Integrated-optic OFDM demultiplexers using optical DFT and FFT circuits"

Dr. Koichi Takiguchi , Professor at Ritsumeikan University in Japan

I was mainly engaged in the research and development of silica planar lightwave circuit (PLC)-based functional devices at NTT Laboratories in Japan from 1992 to 2012. I would like to introduce my last work at NTT, integrated-optic demultiplexers for optical OFDM signals in this seminar. I describe the configuration, operating principle, and characteristics of the demultiplexers, which consist of optical DFT and FFT circuits fabricated with PLC technology.

About Dr. Koichi Takiguchi :

Koichi Takiguchi received a Ph.D. degree in electrical engineering from the University of Tokyo in 1992. He then joined NTT Laboratories where he was engaged in the research and development of silica PLC-based functional devices and high-speed optical transmission systems. In 1995, he realized the first tunable optical dispersion compensator (TODC) by using a silica PLC-based lattice-form optical filter. From 1998 to 1999 he was a visiting scholar at the laboratory of Professor J. E. Bowers in UCSB. In 2012, he joined the Department of Electrical and Electronic Engineering at Ritsumeikan University in Japan as a professor. He is now interested in optical signal processing devices, and their applications to next generation optical communication and sensing systems.
