Very low threshold current operation of all MOCVD grown buried heterostructure 1.3 mu m InAsP/InP strained-layer double quantum well laser diodes is reported for the first time. A very low CW threshold current of 1.8 mA was obtained in a HR coated 200 mu m-long device. The maximum CW operating temperature was 120 degrees C with a characteristic temperature of 62 K in the temperature range 20-60 degrees C.
