Jun-ichi Nishizawa (西澤 潤一, Nishizawa Jun'ichi, September 12, 1926 – October 21, 2018)
He was a professor at Sophia University. He is considered the "Father of Japanese Microelectronics".
Biography
Nishizawa was born in Sendai, Japan, on September 12, 1926. He earned a B.S. in 1948, and a Doctor of Engineering degree in 1960, from Tohoku University.
In 1953, he joined the Research Institute of Electrical Communication at Tohoku University. He became a professor there and was appointed director to two research institutes. From 1990 to 1996, Nishizawa served as the President of Tohoku University.
He became the president of Iwate Prefectural University in 1998.
Research
In 1950, the static induction transistor was invented by Jun-ichi Nishizawa and Y. Watanabe.
In 1952, he invented the
While working at Tohoku University, he proposed fiber-optic communication, the use of optical fibers for optical communication, in 1963.[8] Nishizawa invented other technologies in the 1960s that contributed to the development of optical fiber communications, such as the graded-index optical fiber as a channel for transmitting light from semiconductor lasers.[9][10] He patented the graded-index optical fiber in 1964.[2]
In 1971, he invented the static induction thyristor.[5][11]
