Yasuhiko Arakawa Yasuhiko Arakawa Yasuhiko Arakawa (Japanese , "Arakawa Yasuhiko"; born 6 November 1952) is a Japanese physicist. His research focuses on semiconductor physics, including growth of nanostructures and their optoelectronic applications. Among his main achievements are the proposal of the concept of quantum dots and their application to quantum dot lasers, the observation of exciton-polariton Rabi-splitting in a semiconductor microcavity, or, recently, the first 3D photonic crystal nanocavity lasers with quantum dot gain. Yasuhiko Arakawa received a B.S. degree in 1975 and a Ph.D. degree in 1980, respectively, from the University of Tokyo, both in Electronics Engineering. In 1981 he became
Nihito Arakawa the same event, but a wrist injury forced him to postpone it. That is why Arakawa–Linares was carried live on Showtime pay-per-view. Arakawa was again fighting out of the red corner, but lost in a unanimous decision. In the second half of 2014, he defeated Kondō in their rematch in July, and lost to Katō in their rubber match in December, both by unanimous decision at Korakuen Hall. Arakawa then transferred to Hitoshi Watanabe's Watanabe Boxing Gym in April 2015. Among his new stable-mates are Takashi Uchiyama, Kōhei Kōno and Ryōichi Taguchi. Arakawa's nickname is "The Baby-faced Sniper" because of
