Abstract: The present disclosure relates to an optoelectronic device for manipulating electromagnetic radiation. Drawbacks of conventional systems like material constraints, system complexity and tuning speed are overcome by the optoelectronic device comprising a substrate with at least one tuning structure arranged on the substrate, wherein the tuning structure comprises an electro-optical material. The tuning structure comprises a first and a second electrical contact. A cover layer covers the at least one tuning structure. An optical structure is arranged on the cover layer. A voltage source is electrically connected to the first and the second electrical contact and provided for generating electric fields within the at least one tuning structure.
