Abstract

The use of a 180/spl deg/ (central) grating phase shift has allowed single-mode surface emission in a single-lobe, orthonormal beam pattern from 2nd-order DFB/DBR InGaAs/AlGaAs DQW lasers.
半波光栅相移二阶DFB/DBR激光器的单瓣、正交光束表面发射
使用180/spl度/(中心)光栅相移,可以从二阶DFB/DBR InGaAs/AlGaAs DQW激光器中以单瓣正交光束模式发射单模表面。
