Abstract

A strongly coupled external cavity semiconductor laser with stable frequency operation is reported in this paper. The typical linewidth, maximum tuning range and side-mode suppression ratio of the device are 100 kHz, 120 nm and 35 dB, respectively. The operation frequency is quite stable because of adopting strong external cavity feedback, temperature compensation cavity structure and double-stage temperature control. With the aid of active frequency control loop the frequency shift can be limited within several MHz over 24 hours. More than twenty tunable narrow-linewidth external-cavity semiconductor lasers have been developed in China.
