Yasuharu Suematsu (末松 安晴, Suematsu Yasuharu) is a scientist, who received the Japan Prize and several other notable awards.


Yasuharu Suematsu was born on September 22, 1932, in Gifu, Japan.[2] He received both his B.S. (1955) and Ph.D. (1960) from the Tokyo Institute of Technology.[1][2] Afterwards, he joined the faculty of the Tokyo Institute of Technology as a professor, and became its president in 1989.[1] Later he also held the positions as first[5] President of the newly founded Kochi University of Technology and later became Director General[1] of the National Institute of Informatics. He authored at least 19 books and more than 260 scientific papers.[4]


Professor Suematsu is best known for his contributions to the development of optical fiber communication. He developed semiconductor lasers which even under high-speed modulation produce light at a stable wavelength which coincides with the wavelength region where the optical losses of fibers reach its minimum.[6]
