Susumu Noda, Kyoto Univ. (Japan)

Photonic crystal surface-emitting lasers (PCSELs) are an unprecedented type of semiconductor laser that can achieve single longitudinal- and lateral-mode oscillation even over areas of millimeters in diameter. Their brightness, defined as power per unit area per unit solid angle, is expected to be increased up to the range of 1~10GWcm-2sr-1, which is comparable to those of gas lasers and fiber lasers. Also, PCSELs have additional functions, including the generation of beams with various patterns and polarizations, and they can even achieve electric two-dimensional beam scanning. Material systems for PCSELs are currently being expanded to not only InGaAs/GaAs (900-1000nm), but also InGaAsP/InP (1.3-1.55um) and even InGaN/GaN (400-530nm). LiDAR is discussed as one example of the applications of PCSELs. PCSELs will become a key light source in the forthcoming ultra-smart Society 5.0, which includes smart mobility and smart processing.

Professor Susumu Noda received B.S., M.S., and Ph.D. degrees from Kyoto University, Kyoto, Japan, in 1982, 1984, and 1991, respectively, all in electronics. In 2006, he received an honorary degree from Gent University, Belgium. Currently, he is a full Professor in the Department of Electronic Science and Engineering and a director of Photonics and Electronics Science and Engineering Center, Kyoto University. His research interest covers physics and applications of photonic crystals and quantum nanostructures. He received various awards including the OSA Joseph Fraunhofer Award/Robert M. Burley Prize (2006), Medal with Purple Ribbon (2014), and the Japan Society of Applied Physics Outstanding Achievement Award (2015).

Satoshi Kako, NTT Research, Inc. (United States)

Satoshi Kako is a Senior Research Scientist of the PHI Lab. I received my undergraduate/master’s degrees in electronic engineering from the University of Electro-Communications in 1996/1998. I received my Doctor of Engineering from the University of Tokyo in 2006. I was working on the experimental investigation of optical properties of solid-sate nano-structures. My current research interests are focused on the potential capability and application of coherent network computing.
