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
Mitsu Arakawa over a year before losing to The Crusher and Dick the Bruiser in December 1968. In 1959, Arakawa joined the Indianapolis-based World Wrestling Association (WWA). In October 1966, he defeated Dick the Bruiser to win the WWA World Heavyweight Championship. He lost the championship to Wilbur Snyder in September 1967. Arakawa toured Australia in 1965, 1966 and 1970, winning the IWA World Heavyweight Championship during his first tour. In the mid-1960s, he performed in Canada with Shibuya, with the duo winning the Stampede Wrestling International Tag Team Championship in 1963.
