Abstract :
InAsN/InGaAs multiple quantum wells (MQWs) structures for midinfrared diode lasers is grown on (100) InP substrates by using a VG V-80H gas-source molecular epitaxy (GSMBE). After the GSMBE growth, the laser sample is annealed at 575°C for 20 min under N ambient in order to improve the crystal quality. The PL spectrums of the laser structure before and after annealing are studied. Then the structure is processed into 50-nm-wide broad-area lasers. Laser oscillation under pulsed injection current was obtained from 10K to 260K.
