日本在欧洲的Sharp实验室(SharpLaboratoriesofEurope雪研制成功了世界上第1个用分子束外延(MBE)生长技术生长的蓝-紫激光二极管。采用氮化物半导体材料制作的这种器件可用于下一代Blu-ray标准数字视频光盘(DVD)存储和视频读放装置。在蓝宝石基质上生长的量子阱脊形波导激光器
Sharp’s laboratories in Europe (Sharp Laboratories of Europe) have successfully developed the world’s first blue-violet laser diode grown by molecular beam epitaxy (MBE) growth technology. The device, made of nitride semiconductors, can be used in the next generation of Blu -ray standard digital video disk (DVD) storage and video read-and-playback device.Quantum-well ridge waveguide laser grown on sapphire substrate
