长波长GaInNAs垂直腔面发射激光器

Long-wavelength GaInNAs vertical-cavity surface-emitting lasers

新出现的直接跃迁GaInNAs与具有高反射率的AlAs/GaAs分布布拉格反射镜相结合构成了GaAs基长波长(1.3～1.6μm)垂直腔面发射激光器(VCSEL),将成为光纤通信、光互联和光信息处理等的关键元件。本文从材料的选取、外延技术和GaInNAs VCSEL国外和国内的发展状况等方面对长波长GaInNAs VCSEL进行了综合阐述。

The combination of a novel direct-transition GaInNAs and AlAs/GaAs distributed Bragg reflector with high reflectivity are making up of a GaAs-based long wavelength (1.3～1.6μm) vertical-cavity surface-emitting laser, and the device are becoming the essential element in optical communication, network, and data treatment. We reviewed the long wavelength GaIn-NAs vertical-cavity surface-emitting laser from selection of material, epitaxial technology, and overseas and domestic development of GaInNAs vertical-cavity surface-emitting laser.
