Yasuhiko Arakawa

Yasuhiko Arakawa (Japanese 荒川 泰彦, 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.

Biography
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 an assistant professor at the University of Tokyo and in 1993, was promoted full professor there. He is now at the Institute of Industrial Science, the University of Tokyo and is also the director of Institute for Nano Quantum Information Electronics. He has been a visiting scientist of the California Institute of Technology in the period 1984–1986 and visiting professor at the Technical University of Munich in the period 2009–2011.

He has been a member of the Science Council of Japan since 2009.

He was also elected as a member into the National Academy of Engineering in 2017 for contributions to quantum dot lasers and related nanophotonic devices.
