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 and his wife Lydia have visited the school. Two Rivers is served by Two Rivers High School, built in 2002 to replace the now-demolished Washington High School. The school houses a photography darkroom and a television broadcast room for hands-on experience. The high school's daily announcements are broadcast by students on the city's public access television channel. The school's sports include swimming, football, track and field, baseball, soccer, and others. Some students from Two Rivers also attend Roncalli High School and Manitowoc Lutheran High School in nearby Manitowoc. Two Rivers is part of the Green Bay, Wisconsin television market, as
