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
Shizuka Arakawa Slutskaya. Cohen fell twice during her long program, leaving the door open to the other leaders. Arakawa won the free program, skating to Vanessa Mae's Violin Fantasy on Puccini's Turandot by Giacomo Puccini. She performed an Ina Bauer and then did a three jump combination. "Ina Bauer" became a household word in Japan as a result. Although she had planned two triple-triple combinations for the free skate, she did not perform them, doing instead a triple Lutz-double loop and a triple salchow-double toe loop combinations. Arakawa earned a total combined score of 191.34 points, almost eight points ahead of the
