Jun-ichi Nishizawa (西澤 潤一), “Mr. Semiconductor” and “Father of Optical communication”, is famous worldwide as a creative researcher in semiconductor engineering.
He invented a prototype of a semiconductor laser in 1957, invented three major elements of an optical communication system (photodiode– light receiving element, semiconductor laser — light emitting element, and optical fiber), and made the outline of the concept of the optical communication system.
He received the Jack A. Morton Award, the most prestigious award in the electronic engineering field, for the first time received by Japanese. In 2002, the Institute of Electrical and Electronics Engineers (IEEE. U.S.A.), the world’s largest academic society, founded the “Jun-ichi Nishizawa Medal” as the 14th IEEE medal, comparable to the IEEE Edison Medal or the IEEE Alexander Graham Bell Medal. A IEEE Medal is one of the most prestigious awards.
