High T/sub 0/ 1.3 /spl mu/m AlGaInAs/InP distributed feedback laser with complex-coupled grating growth by LP-MOCVD

A high T/sub 0/ 1.3 /spl mu/m AlGaInAs-InP MQW DFB laser, which was grown by LP-MOCVD, is demonstrated for the first time. The T/sub 0/ is up to 98K and the drop of 0.5dB in slope efficiency is achieved within 20 C to 80 C. A DFB laser with current blocking grating was realized successfully.
