A high performance ridge-waveguide InAs/InP quantum dot distributed feedback laser around 1.52 um with a cavity length of 1 mm and a stripe width of 3 um 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 2154 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 188C.Peer reviewed: YesNRC publication: Ye
