Abstract

We report on successful fabrication of GaSb-based type-I quantum well distributed Bragg reflector (DBR) lasers emitting around 2.3μm. Second-order Bragg gratings of chromium were patterned by electron beam lithography. For 1.5-mm-long laser diode, single mode continuous-wave operation with output power of 10mW is obtained. The devices show a stable single mode operation with high side mode suppression ratio.

分布布拉格反射激光器发射约2.3μm

本文报道成功制备了发射波长约2.3μm的基于gasb的i型量子阱分布布拉格反射器(DBR)激光器。采用电子束光刻技术对铬的二阶布拉格光栅进行了图案化。对于1.5 mm长的激光二极管，可获得输出功率为10mW的单模连续波工作。器件单模工作稳定，侧模抑制比高。
