A high performance ridge-waveguide InAs/InP quantum dot distributed feedback laser around 1.52 µm with a cavity length of 1 mm and a stripe width of 3 µm is demonstrated. In continuous-wave operation singlemode output power was up to 18.5 mW and its sidemode suppression ratio was greater than 62 dB. The relative intensity noise was measured to be less than −154 dB/Hz from 10 MHz to 10 GHz, and the optical linewidth smaller than 150 kHz when the injection current was 200 mA at room temperature of 18°C.
