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
Two Rivers, Wisconsin derives its name from the East Twin River and the West Twin River which meet in the city less than a mile from their outflows at Lake Michigan. Two Rivers is located at (44.154928, −87.57642). According to the United States Census Bureau, the city has a total area of , of which, is land and is water. Two Rivers, Wisconsin lies within the humid continental climate zone, modified by its close proximity to Lake Michigan. This gives the city more moderate temperatures and lesser extremes compared to its inland counterparts. The lake influence also gives Two Rivers a greater seasonal
