Abstract

An optoelectronic component includes a layer structure including an active zone that generates electromagnetic radiation and is arranged in a plane, wherein the layer structure includes a top side and four side faces, first and third side faces are arranged opposite one another, second and fourth side faces are arranged opposite one another, a strip-shaped ridge structure is arranged on the top side of the layer structure and extends between the first side face and the third side face, the first side face constitutes an emission face for electromagnetic radiation, wherein a first recess is introduced into the top side of the layer structure laterally alongside the ridge structure, a second recess is introduced into the first recess, the second recess extends as far as the second side face, and at least one third recess is introduced into a base face of the first recess laterally alongside the ridge structure.
