Abstract
The invention concerns an optoelectronic component comprising a layer stack that includes at least two active zones and a carrier that is applied to the layer stack. The invention further concerns a method of fabricating such an optoelectronic component.
Claims18
An optoelectronic component, comprising a layer stack that includes at least two active zones and comprises a carrier applied to said layer stack,
- wherein the active zones are positioned in vertical alignment with respect to one another and parallel to said carrier to form a stack of active zones;
- wherein each zone of the at least two active zones generates electromagnetic radiation having a different wavelength when a current is applied to the zone;
- wherein the stack comprises pairs of active zones, each pair of active zones being contacted with a common contact layer positioned between the pair of active zones;
- and
- wherein said active zones can be contacted independently.
2 more elements
A device, comprising:
- a layer stack comprising at least two active layers, each one of the at least two active layers being offset with respect to the other active layers in a first direction and configured to emit radiation in the first direction,
- wherein each one of the at least two active layers comprises an independent electrical connection comprising a first electrical contact formed by a contact layer of the stack and a second electrical contact formed by a different contact layer of the stack, at least one of the contact layers for each active layer being a common contact layer for another of the active layers.
