Hayashi Izuo

Hayashi Izuo ( Japanese 林 厳 雄 ; * May 1, 1922 in Tokyo Prefecture ; † September 26, 2005 ) was a Japanese physicist who dealt with semiconductor lasers .

Hayashi studied physics at the University of Tokyo with a master’s degree in 1946. Afterwards he was there from 1955 assistant professor at the Institute for Nuclear Research at the University of Tokyo and received his doctorate in 1962. As a post-doctoral student , he spent a year at the Massachusetts Institute of Technology in 1963 and then from 1964 to 1971 at Bell Laboratories , where he worked on semiconductor lasers. He continued this from 1971 at the NEC research laboratories. From 1982 to 1987 he was senior scientist at the Optoelectronics Joint Research Laboratories and from 1987 to 1994 director of the Optoelectronics Technology Research Laboratory in Tsukuba . In 1996 he retired.

Together with Morton Panish at Bell Laboratories in 1970, he was part of the team that made the first practical semiconductor lasers (continuous operation at room temperature) work independently of a Russian group at the Joffe Institute ( Shores Iwanowitsch Alfjorow ), who reached their goal a little earlier .
