Optoelectronic component and illumination device

An optoelectronic component comprising:

• a semiconductor body having an active region that generates primary electromagnetic radiation and an exit surface;
• an optical element arranged downstream of the exit surface that deflects and/or converts radiation generated in the component;
• and
• a dielectric mirror between the exit surface and the optical element,
• wherein the dielectric mirror is transmissive to radiation of a predetermined wavelength generated in the component and incident at angles of incidence in a predetermined first angular range, and is reflective to the radiation of the predetermined wavelength incident at angles of incidence in a predetermined second angular range.

An optoelectronic component comprising:

• a semiconductor body having an active region that generates primary electromagnetic radiation and an exit surface;
• a meta lens located downstream of the exit surface;
• and
• a polarization filter between the meta lens and the exit surface,
• wherein the meta lens is formed from at least two materials of different refractive indices, and
• the materials are arranged in succession along the main extension plane so that the meta lens has a patterning in refractive index in directions parallel to its main extension plane.
