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

Rather than writing another fantasy series like "Fullmetal Alchemist", Arakawa wanted to challenge herself by trying a more realistic story with "Silver Spoon". It quickly rose among Shogakukan's best-selling titles and an anime series by A-1 Pictures began airing in July 2013. Also in July 2013 she began her manga adaptation of Yoshiki Tanaka's "The Heroic Legend of Arslan" series of novels in Kodansha's "Bessatsu Shōnen Magazine".
