Abstract :
We have achieved a continuous-wave (cw) lasing operation of GaInNAs/GaAs quantum well lasers grown by chemical beam epitaxy (CBE) up to 90°C. Lasing wavelength was 1.20 μm at room temperature and the threshold current density was 1.6 kA/cm2 for a 50 μm width and 170 μm-long device. A characteristic temperature T0 of 150 K (10-90°C, cw) was demonstrated. Temperature characteristics for different lasing wavelength were also investigated under pulsed condition. A 1.3 μm laser still showed T0 of 190 K (25-50°C)
