Abstract
In an embodiment an optoelectronic device includes an epitaxial layer stack having at least a first epitaxial layer and a second epitaxial layer arranged above the first epitaxial layer, wherein the following layers are embedded in the epitaxial layer stack a first semiconductor layer of a first conductivity type, an active layer arranged above the first semiconductor layer and configured to generate light, and a second semiconductor layer of a second conductivity type arranged above the active layer, wherein an interface between the first epitaxial layer and the second epitaxial layer extends at least partially through the first semiconductor layer and/or the second semiconductor layer, and wherein the active layer is embedded in a non-doped barrier layer, the barrier layer covering one or more side surfaces of the active layer.
