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
Shusaku Arakawa formed a close friendship. He started using diagrams within his paintings as philosophical propositions. Jean-Francois Lyotard said of Arakawa's work that it "makes us think through the eyes," and Hans-Georg Gadamer described it as transforming "the usual constancies of orientation into a strange, enticing game—a game of continually thinking out." Quoting Paul Celan, Gadamer also wrote of the work: "There are songs to sing beyond the human." Charles Bernstein and Susan Bee observe, "Arakawa deals with the visual field as discourse, modal systems that constitute the world rather than being constituted by it." Arthur Danto found Arakawa to be "the
