GaN基板上GaN系半導体レーザーの現状 Current Status of GaN-Based Laser Diodes Grown on Freestanding GaN Substrate
The development of optical memory devices that use violet laser diodes (LDs) has progressed significantly and these devices have been commercialized. The need for high-speed recording and multilayer recording is increasing, and it is expected that even higher power LDs will be necessary in the future. In this paper, the current state of GaN-based LD research for the next generation optical memory devices is reported, and next targets are discussed. Moreover, we developed high power pure blue laser diodes for full-color laser display. The details of these pure blue LDs characteristics are reported.
