Abstract :
A simulation model for tapered lasers with separated contacts has been developed. The model has been used to simulate 980 nm In-Ga-As devices with separated injection of the ridge-waveguide and taper sections. A good qualitative agreement with experimental results has been obtained. The physical origin of the observed improvements in the beam quality by stronger pumping of the ridge waveguide section is discussed.
