Abstract
Strained layer InGaAs/GaAs SCH SQW (Separate Confinement Heterostructure Single Quantum Well) lasers were grown by Molecular Beam Epitaxy (MBE). Highly reliable CW (continuous wave) 980 nm, broad contact, pump lasers were fabricated in stripe geometry using Schottky isolation. Threshold current densities of the order of J/sub th//spl ap/280 A/cm/sup 2/ (for a resonator length L=700 /spl mu/m) and differential efficiency /spl eta/=0.4 W/A (41%) were obtained. The wall-plug efficiency was 38%. Theoretical estimations of these quantities obtained by numerical modelling of devices were J/sub th/=210 A/cm and /spl eta/=0.47 W/A respectively.
