Abstract:
A semiconductor laser component, comprising:a semiconductor body having a heterostructure configuration suitable for generating an electromagnetic radiation, said heterostructure configuration including:a semiconductor substrate;a first outer cover layer of a first conductivity type disposed above said semiconductor substrate;a second outer cover layer of the first conductivity type disposed above said semiconductor substrate;an active zone layer sequence with a quantum well structure disposed between said first and second outer cover layers, for generating the electromagnetic radiation in said quantum well structure when current flows through said semiconductor body; anda charge carrier injector for accelerating charge carriers within an internal electrical field and thereby injecting the charge carriers rapidly into said active zone layer, said charge carrier injector having a first highly doped denatured transition layer of a second conductivity type opposite the first conductivity type and a second highly doped denatured transition layer of the first conductivity type, disposed between said active layer sequence and said second outer cover layer, said second highly doped denatured transition layer disposed between said first highly doped denatured transition layer and said second outer cover layer.
