Abstract:
A vertical-resonator-laser-diode, comprising:first and second electrical contact layers; a first Bragg-reflector-layer-sequence and a second Bragg-reflector-layer-sequence disposed between said first and second electrical contact layers, each having a plurality of mirror-pairs; an active layer-sequence being assembled between said first and second electrical contact layers and between said first Bragg-reflector-layer-sequence and said second Bragg-reflector-layer-sequence for creating a laser-radiation; said first Bragg-reflector-layer-sequence and second Bragg-reflector-layer-sequence forming a laser-resonator; at least one of said Bragg-reflector-layer-sequences being semi-transparent for said laser-radiation, thereby forming a semi-transparent Bragg-reflector-layer-sequence; and at least one light-absorbing layer being assembled with a given light-absorption on said semi-transparent Bragg-reflector-layer-sequence on the light-outlet-side.
