Abstract(in Japanese) (See Japanese page)
Abstract(in English) We have fabricated blue-violet laser diodes, consisting of nitride-based semiconductors, with both high-power and low-noise characteristics on GaN substrates. By improving the crystal quality of the grown materials and optimizing the optical confinement in the device, a kink level as high as 250 mW has been achieved. These laser diodes have been operating reliably for more than 1OOOh with a light output power of 100 mW at 60℃ under pulsed operation. We have also confirmed that these laser diodes have a noise level as low as -130dB/Hz, which meets the requirement for practical use, for a light output power of 5mW. These laser diodes are expected to enable dual layer recording in next -generation, large-capacity optical disc systems using blue-violet laser diodes.
