Two-component spatially inhomogeneous (GaAl)As heterojunction laser

A semiempirical model is used to calculate the watt-ampere characteristics and phase diagrams of heterojunction lasers with spatially inhomogeneous injection. Experimental results were reported of a study of the region of "smooth" turn-on, bistability, and self-modulation in two-component (GaAl)As stripe heterojunction lasers capable of operating continuously at room temperature. The experimental results are compared with calculations, and with similar characteristics of cooled two-component homojunction lasers.
