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 well as the Sheboygan/Manitowoc Arbitron radio market. The city is home to WCUB-AM and WGBW-AM. Charter Communications provides cable service for the city. There is a heated debate between Ithaca, New York and Two Rivers over which city has the right to claim the title "birthplace of the ice cream sundae." When Ithaca mayor Carolyn K. Peterson proclaimed a day to celebrate her city as the birthplace of the sundae, she received postcards from Two Rivers' citizens reiterating that town's claim. Ithaca retaliated with an ad called "Got Proof?" in the Two Rivers newspaper. Two Rivers' claim is based on
