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 second-place Cohen (183.36). Like Cohen, Slutskaya made mistakes in her long program, and ended up taking bronze, leaving Arakawa as the gold medal winner, which was also Japan's only medal of the 2006 games. Slutskaya was third at 181.44. At age 24, Arakawa became the oldest women's Olympic skating champion in more than 80 years. Florence "Madge" Cave Syers from the United Kingdom was the oldest when she won the Olympic title at age 27 at the 1908 Summer Olympics, which featured the first Olympic figure skating events. After winning her Olympic title, Japanese Prime Minister Junichiro Koizumi called Arakawa
