2021 - OSA Fellows Yoshitomo Okawachi Columbia University, USA For pioneering contributions to slow light based on stimulated scattering and chip-based optical frequency combs
His primary scientific interests are in Optics, Optoelectronics, Frequency comb, Laser and Broadband. As a member of one scientific family, he mostly works in the field of Optics, focusing on Silicon nitride and, on occasion, Metrology. His Optoelectronics study focuses on Photonic-crystal fiber in particular.
His study in Frequency comb is interdisciplinary in nature, drawing from both Four-wave mixing, Nonlinear optics and Resonator. He works mostly in the field of Laser, limiting it down to concerns involving Soliton and, occasionally, Laser pumping, Comb generator and Terahertz radiation. Yoshitomo Okawachi works mostly in the field of Broadband, limiting it down to topics relating to Silicon and, in certain cases, Optical parametric amplifier, as a part of the same area of interest.
Yoshitomo Okawachi mostly deals with Optics, Optoelectronics, Frequency comb, Silicon and Dispersion. His research in Four-wave mixing, Supercontinuum, Nonlinear optics, Wavelength and Resonator are components of Optics.
