摘要：

Continuous wave operation of GaInP/AlGaInP DFB lasers at room temperature is reported. The DFB lasers in ridge waveguide geometry show stable singlemode emission with a sidemode suppression > 30dB and a threshold current of 25.9mA at 20 degrees C. Singlemode operation could be achieved for a large temperature range between -10 and 40 degrees C. Even for 40 degrees C the threshold current remains below 50mA.
