High-power, high-beam-quality, high-functionality photonic-crystal surface-emitting lasers－For paradigm shift towards realizing smart society
Realization of single-mode, high-power and high-beam-quality (namely, high-brightness) semiconductor lasers, which can rival or even replace bulky lasers such as gas and solid-state lasers, is one of the ultimate goals of laser physics and photonics. The demand for such ultimate single-mode high-brightness semiconductor lasers is increasing for a wide variety of emerging applications including next-generation remote sensing for smart mobility and high-precision laser processing for smart manufacturing. Photonic-crystal surface-emitting lasers (PCSELs) show promise to meet these demands, based on their broad-area coherent two-dimensional (2D) resonance at a singularity (G) point of their 2D photonic band structure. In this plenary talk, recent progress in PCSEL development, including the formulation of a design guideline for realizing 100W-to-kW-class single-mode operation, the experimental demonstration of a brightness of 1GWcm-2sr-1 are described. In addition, various functionalities such as 2D beam steering and emissions of arbitrary beam patterns are also discussed.
About the Speaker
Prof. 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, and the Honorary degree from Gent University, Belgium, in 2006. From 1984 to 1988, he was with the Mitsubishi Electric Corporation, and joined Kyoto University in 1988.
