Abstract
In an embodiment an optoelectronic device includes a layer stack having a circumferential sidewall region and having an n-doped layer, an active region layer deposited on the n-doped layer, the active region layer having a central first portion and a surrounding second portion, a p-doped layer arranged on the active region layer, wherein the surrounding second portion comprises a p-type dopant causing a quantum well intermixing in the surrounding second portion and a thin n-doped surface layer on the circumferential sidewall extending from the n-doped layer substantially towards a top of the p-doped layer thereby forming an artificial pn-junction substantially parallel to the circumferential sidewall region and at least partially within the surrounding second portion and the p-doped layer.
