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
Minoru Arakawa and office buildings. At a Christmas party in Kyoto, Arakawa met Yoko Yamauchi, daughter of Nintendo president Hiroshi Yamauchi. They married in November 1973. Arakawa, along with his wife and three-year-old daughter Maki, moved to Vancouver, Canada in 1977 for work. A second daughter, Masayo was born in 1978. Hiroshi Yamauchi offered Arakawa to establish Nintendo of America; while Yoko opposed the position, having seen the impact of the company on her father's life, Arakawa accepted the offer. Arakawa and his wife established an office in Manhattan in 1980, and Arakawa became the company's first president. After a disastrous experience
