Taiichi Otsuji received the Dr. Eng. degree from Tokyo Institute of Technology, Japan in 1994. He has been a professor at the Research Institute of Electrical Communication, Tohoku University, Japan since 2005 after working for Kyushu Inst. Tech. (1999-2005) and NTT Laboratories (1984-1999), Japan. He is authored and co-authored more than 240 peer-reviewed journals. He was awarded the Outstanding Paper Award of the 1997 IEEE GaAs IC Symposium, and an IEEE Electron Device Society Distinguished Lecturer in 2013. He is a Fellow of the IEEE, a senior member of the OSA, and a member of the JSAP, MRS, and IEICE.


IntroductionGraphene has attracted attention due to its massless and gapless energy spectrum. Carrier-injection pumping of graphene enables negative-dynamic conductivity in the terahertz (THz) range, which may lead to new... [ view full abstract ]
