讨论了影响激光器高温特性的主要因素 ,提出了在 1 .3μm高温无致冷 Al Ga In As应变量子阱激光器中采用倒台脊波导 ( RM- RWG)结构可以改善激光器高温无致冷的工作特性 ,研制出了 RM- RWG结构的 1 .3μm高温无致冷 Al Ga In As应变量子阱激光器 ,其阈值电流为 6m A,特征温度达到 95 K( 2 5℃～ 85℃ ) 。

In this paper, the high temperature properties of 1.3 μm laser diode are discussed. The reverse mesa RWG structure is introduced into 1.3 μm AlGaInAs/InP MQW LD and applied to fabricate the uncooled laser diode with high performance and improved temperature characteristics. The threshold current as low as 6 mA, and characteristics temperature as high as 95 K between 25 ℃ and 85 ℃ are obtained, which are the best results in the literatures until now.
