Tatsuo Izawa (Japanese: 伊澤 達夫; born December 24, 1941) is a Japanese researcher known for his work on fiber-optic communication.
Early life and education
Izawa was born on December 24, 1941 in Tokyo. During World War II, his family temporarily moved to a rural area of Nagano Prefecture, before returning to Tokyo. He attended Tokyo Metropolitan Nishi High School and entered the University of Tokyo in 1961.[1]
He received a Bachelor of Engineering degree from the University of Tokyo in 1965 and completed a doctorate in electronic engineering there in 1970.[2][3]
Career
After completing his doctorate in 1970, Izawa joined the Electrical Communication Laboratories of the Nippon Telegraph and Telephone Public Corporation.[3][2] At the Musashino laboratory, he studied semiconductor lasers dynamics and the use of electromigration to alter the refractive index of glass.[1]
Izawa later began investigating the production of low-loss optical fiber. He spent about a year as a visiting researcher at the University of California, Berkeley, studying metal-insulator structures and infrared detectors. He then returned to NTT and transferred to its Ibaraki laboratory in 1975.[1][4] Izawa devised the VAD method in 1977.[5]
In 1998, Izawa became president, and chief executive officer of NTT Electronics, an NTT subsidiary that manufactured optical and electronic components. He became a corporate adviser in 2004 and a senior adviser in 2007.[2][6]
In 2007, Izawa joined the Tokyo Institute of Technology as executive vice president responsible for research and industry collaboration.[2][3]
Izawa later served as president and chair of the governing board of the Chitose Institute of Science and Technology.[7][4]
Honors and awards
Izawa received an achievement award from the International Society for Optical Engineering in 1980. In 1982, he received Japan's Imperial Invention Award for his optical-fiber research.[3] He was awarded the Medal with Purple Ribbon by the Japanese government in 1998.[3]
In 2001, Optica and the IEEE Lasers and Electro-Optics Society awarded Izawa the John Tyndall Award for his contributions to optical-fiber technology. He was elected a Fellow of Optica in 2002.[3]
Izawa was elected a foreign member of the United States National Academy of Engineering in 2004. His election citation recognized his invention and refinement of the VAD method for manufacturing optical fiber.[7]
In 2007, Izawa shared the C&C Prize with Robert D. Maurer of Corning and John B. MacChesney of Bell Labs. The NEC C&C Foundation recognized the three engineers for their respective pioneering contributions to the development and manufacture of low-loss optical fiber.[8]
