# Akira Hasegawa

> Akira Hasegawa  was a Japanese theoretical physicist and engineer who worked in the U.S. 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.
