Abstract

We report on photonic crystal lasers (PCSELs) with high power and high beam quality. The PCSELs have been developed with AI-assisted technologies. The developed devices with a 500µm diameter successfully oscillated with a high, 10W-class peak output power and a very narrow divergence angle of 0.1°. This fact indicates that the devices operate in a complete single lateral and longitudinal mode even over the large area of 500µm diameter. The devices have been installed in time-of-flight LiDAR system. Very high-resolution operation has been successfully realized even though a lens system is not utilized, clearly demonstrating the advantage of high-brightness PCSELs.
