Abstract

In an embodiment a light-emitting component includes a housing and an edge emitting semiconductor laser arranged in the housing, wherein the semiconductor laser is configured to emit light at a side face in an angle range, wherein the housing includes an emission opening for emitting the light, wherein the semiconductor laser is arranged in a first layer having a first material, wherein a second layer is arranged on the first layer, the second layer having a second material, wherein the first layer and the second layer are transmissive to the light, wherein the second layer is arranged between the first layer and the emission opening, wherein the emission opening lies at least partly outside the angle range of the semiconductor laser, and wherein a part of the light is directed directly onto an interface between the first and second layers.
