Abstract :
The first fabrication is reported of a buried ridge structure Ga0.8In0.2As/GaAs/Ga0.51In0.49P laser emitting at 0.98 mu m grown by two-step low pressure metal organic chemical vapour deposition. The width of the ridge is 2 mu m. Laser output power greater than 40 mW with a threshold current of 30 mA has been measured. A typical quantum efficiency of eta =60% was obtained without any facet coating. Excellent homogeneity and uniformity have been achieved over a wafer area of 10 cm2.
