Amnon Yariv (born 1930) is an Israeli-American professor of applied physics and electrical engineering at Caltech in Pasedena, CA. He received his B.S in 1954, his M.S. in 1956, and his Ph.D. in 1958, all from the University of California, Berkeley.
His research focuses on the theoretical and technological underpinning of optical communication. Some projects include: developing new types of semiconductor lasers, optical phase-lock systems and coherent photonics, hybrid Si/III-V devices for lasers, detectors and modulation, "Slow" light propagation in artificial periodic dielectric waveguides. The highlight of his group's work was the invention of the semiconductor distributed feedback laser, a device widely used in the Internet's fiber-optic communications.
He has been a member of the National Academy of Sciences since 1991. In 1985 he was awarded the Harold Pender Award by the University of Pennsylvania. In 1992 he was awarded the Harvey Prize by the Technion in Haifa, Israel, for "pioneering contributions to opto-electronics, wave propagation in crystals and nonlinear and phase-conjugate optics, and his demonstration of semiconductor-based integrated optics technology leading to the development of high-speed and stable solid-state lasers". In 2010, he was selected as a winner of the National Medal for Science and received the IEEE Photonics Award in 2011.
