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
Billy Two Rivers star, and that people wanted to see him because he was "an attraction". He was successful, however, and his time in the United Kingdom, where Paul LeDuc has stated that Two Rivers was "treated like a God", helped him become an "international star". Two Rivers returned to the United States in September 1965 and resumed wrestling in North Carolina. After six months, which included teaming with Karl Gotch to defeat the Blond Bombers (Rip Hawk and Swede Hanson), Two Rivers left the territory to compete in Japan. He competed there until at least May 13, 1966, after which point there
