Abstract: A laser light source, comprising a semiconductor layer sequence on a substrate and having an active region and a radiation coupling out area having first and second partial regions and a filter structure. The active region generates coherent first electromagnetic radiation and incoherent second electromagnetic radiation, the coherent first electromagnetic radiation is emitted by the first partial region along an emission direction, the incoherent second electromagnetic radiation is emitted by the first partial region and by the second partial region. The filter structure at least partly attenuates the incoherent second electromagnetic radiation emitted by the active region along the emission direction. The filter structure has at least one filter element arranged on an area of the semiconductor layer sequence which has an extension direction parallel to the emission direction and which is remote from the substrate.

Abstract: A method for producing an optoelectronic component is disclosed. A first layer which has a dielectric to the surface of a semiconductor crystal. A photoresist layer is applied and structured on the first layer. The photoresist layer is structured in such a way that the photoresist layer has an opening, The first layer is partially separated in order to expose a lateral region of the surface. A contact area having a first metal is applied in the lateral region of the surface. The photoresist layer is removed. A second layer, which comprises an optically transparent, electrically conductive material, and a third layer, which comprises a second metal, are applied.
