Okawachi Named a 2021 OSA Fellow

Dr. Yoshitomo Okawachi was named a 2021 Fellow of The Optical Society (OSA) "for pioneering contributions to slow light based on stimulated scattering and chip-based optical frequency combs." The OSA awarded this distinction to "118 OSA members, from 24 countries, for their significant contributions to the advancement of optics and photonics through education, research, engineering, business leadership and service." (OSA)

Dr. Okawachi is a Research Scientist in the APAM Department at Columbia Engineering and is a member of Prof. Alexander Gaeta's Quantum and Nonlinear Photonics Group. Dr. Okawachi's research interests include optical frequency comb generation in silicon-based waveguides and microresonators, coherent computing based on degenerate optical parametric oscillation in microresonators, parametric nonlinear interactions in photonic devices, slow light, and all-optical signal processing using space-time duality techniques. He earned his PhD in Applied Physics at Cornell University 2008. In 2017, he was named an OSA Ambassador and received the Tingye Li Innovation Prize. In 2021, he was also named Chair-Elect for the Optical Society's Integrated Photonics Technical Group.
