Abstract
High power InGaAs-GaAs distributed feedback (DFB) lasers with nonabsor bing mirrors have been fabricated with over 200mW of single frequency CW optical pou;er at 25 degrees C (110mW at 95 degrees C). Unlike thei r distributed Bragg reflector counterparts, the DFB devices exhibit re latively linear optical power against current curves. Low threshold cu rrents of similar to 10mA were also obtained.
