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
Shizuka Arakawa a disappointment which she later credited as a motivation to stay in the sport and regain top form. She felt she could not quit on such a down note. In November 2005, Arakawa changed coaches to Nikolai Morozov. At the 2006 Winter Olympics in Turin, Italy, Arakawa skated in the short program to Fantaisie-Impromptu by Chopin. She went into the long program in third place, behind pre-event favorites Sasha Cohen and Irina Slutskaya. Less than a point separated the top three skaters. In the long program, Cohen was the first of the three leaders to skate, followed by Arakawa and
