ABSTRACT:
In a stripe-geometry multimode laser having a current-flow-determining stripe, only the flow of electric current is confined to a narrow area, while the heat can flow off through a large area. A window for the flow of electric current is formed by a narrow epitaxial semiconductor stripe which, because of its high doping level and of additionally diffused charge carriers, is highly conductively connected to both the underlying semiconductor and the overlying metal, while next to the stripe, electric conductivity from the semiconductor to the metal is very poor. The thermal conductivity, however, is approximately the same over the entire area.
