Abstract
In an embodiment an optoelectronic arrangement includes an optoelectronic component having a layer stack including an active area arranged between a layer of a first conductive type and a layer of a second conductive type, a substrate configured to generate an alternating electrical field at a surface of the substrate, the alternating electrical field having opposing field components and at least one first excitation element arranged on or within the substrate, wherein the optoelectronic component is arranged on the substrate such that the opposing field components of the alternating electrical field are substantially perpendicular to respective layers of the layer stack.

An optoelectronic arrangement comprising:
- an optoelectronic component comprising a layer stack including an active area arranged between a layer of a first conductive type and a layer of a second conductive type;
- a substrate configured to generate an alternating electrical field at a surface of the substrate, the alternating electrical field having opposing field components;
- and
- at least one first excitation element arranged on or within the substrate,
- wherein the optoelectronic component is arranged on the substrate such that the opposing field components of the alternating electrical field are substantially perpendicular to respective layers of the layer stack.
A method for contactless supplying energy to an optoelectronic component, the optoelectronic component having an active area arranged between a first layer and a second layer of different conductivity types, the method comprising:
- generating a surface acoustic wave having a wavelength on a surface of a substrate, wherein at least a portion of an electrical field extends above the surface and comprises a field component substantially parallel towards the surface;
- and
- exerting a force by the field component in the first and second layers of the optoelectronic component such that, during a first half-period of the wavelength, charge carriers within the first and second layers are forced towards the active area and, during a second half-period of the wavelength, the charge carriers within the first and second layers are forced away from the active area.
