| dbo:abstract | Hayashi Izuo (jap. 林 厳雄; * 1. Mai 1922 in der Präfektur Tokio; † 26. September 2005) war ein japanischer Physiker, der sich mit Halbleiterlasern befasste. Hayashi studierte Physik an der Universität Tokio mit dem Master-Abschluss 1946. Danach war er dort ab 1955 Assistenzprofessor am Institut für Kernforschung der Universität Tokio und wurde 1962 promoviert. Als Post-Doktorand war er 1963 ein Jahr am Massachusetts Institute of Technology und danach 1964 bis 1971 an den Bell Laboratories, wo er sich mit Halbleiterlasern befasste. Das setzte er ab 1971 an den NEC Forschungslaboratorien fort. 1982 bis 1987 war er leitender Wissenschaftler der Optoelectronics Joint Research Laboratories und 1987 bis 1994 Direktor des Optoelectronics Technology Research Laboratory in Tsukuba. 1996 ging er in den Ruhestand. Er gehörte mit Morton Panish 1970 an den Bell Laboratories zu dem Team, das unabhängig von einer russischen Gruppe am Joffe-Institut (Schores Iwanowitsch Alfjorow), die etwas früher ans Ziel gelangten, die ersten praktikablen Halbleiterlaser (kontinuierlicher Betrieb bei Zimmertemperatur) zum Laufen brachten. (de) Izuo Hayashi (林 厳雄, Hayashi Izuo) (May 1, 1922 – September 26, 2005) was a Japanese physicist. Hayashi was born in Tokyo in 1922 and graduated from the faculty of science, University of Tokyo in 1946. He worked as assistant professor at the Institute for Nuclear Research of the same university and defended his PhD in 1962. After the PhD defense, he stayed for a year at MIT, and between 1964 and 1971 worked at Bell Labs on semiconductor lasers. In 1971 he joined the Research Laboratories of NEC where he continued his studies of semiconductor lasers, aiming to improve their reliability and lifetime. Between 1982 and 1987 he was a head scientist at NEC and in 1987–1994 became director of the Optoelectronics Technology Research Laboratory in Tsukuba. From 1994 until retirement in 1996 he served as advisor in the same laboratory. Hayashi died of acute leukemia in 2005.
