Abstract
A semiconductor optical component is disclosed which includes a semiconductor material confinement layer containing acceptor dopants such that the doping is p-type doping. The confinement layer is deposited on another semiconductor layer and defines a plane parallel to the other semiconductor layer. Furthermore, the p-type doping concentration of the confinement layer has at least one gradient significantly different from zero in one direction in the plane. A method of fabricating the component is also disclosed.
