Claim:
1. An optoelectronic device having a semiconductor layer structure comprising: a substrate; a first light-active layer and a second light-active layer, wherein a first tunnel junction is formed between the first light-active layer and the second light-active layer, wherein a first Bragg reflector is formed between the first light-active layer and the first tunnel junction, and wherein a second Bragg reflector is formed between the second light-active layer and the first tunnel junction; wherein at least a portion of an electromagnetic radiation emitted by the first light-active layer leaves the optoelectronic device via the substrate, wherein the optoelectronic device is a light emitting diode, and wherein at least a portion of the electromagnetic radiation emitted in the semiconductor layer structure leaves the optoelectronic device through a surface of the semiconductor layer structure that faces away from the substrate.
