Akira Hasegawa

Akira Hasegawa (Japanese: 長谷川晃, Hepburn: Hasegawa Akira, born June 17, 1934 in Tokyo Prefecture) is a theoretical physicist and engineer who has worked in the US and Japan. He is known for his work in the derivation of the Hasegawa–Mima equation, which describes fundamental plasma turbulence and the consequent generation of zonal flow that controls plasma diffusion. Hasegawa also made the discovery of optical solitons in glass fibers, a concept that is essential for high speed optical communications.
