Yasuhiro Koike received his Ph.D. in Engineering from the Graduate School of Engineering, Keio University, Yokohama, Japan. He served as a visiting research staff at AT&T Bell Laboratories from 1989 to 1990. He has been Professor at Keio University since 1997. He specializes in “photonics polymer” that is represented by the high-bandwidth graded-index polymer optical fiber (GI POF), highly scattered optical transmission (HSOT) polymer, zero birefringence polymer. He has been pursuing an R&D project of Face-to-Face Communication system using the photonics polymer technologies in the Funding Program for World-Leading Innovative R&D on Science and Technology (FIRST program) of the Cabinet Office of Japan since 2010. He received the International Engineering and Technology Award of the Society of Plastics Engineers in 1994, the Fujiwara Award in 2001, and an honor of Medal with Purple Ribbon in Palace in 2006. In 2007, he was conferred as an honorary doctorate from Eindhoven University of Technology.Novel Photonics Polymer for Face-to-Face CommunicationRecent progress and status of photonic polymers for overwhelmingly realistic face-to-face communication are described. The world’s fastest graded-index plastic optical fiber covering 40gbps which is directly connected to large size display realizes high realistic sensation without any time lag. The 3D/4K display has been successfully made by a highly scattered optical transmission polymer, which increases the brightness and contrast, and by an invention of zero-birefringence polymer that dramatically improves the control of polarization phase and dissolves the mura problem at low fabrication cost. The key technology is the photonic polymer which will totally change the communication system of today.
