Patent ID: 7683449

Claim:
An optoelectronic component comprising: a semiconductor device comprising at least three radiation-sensitive zones that are formed in silicon and configured to detect electromagnetic radiation; and an optical element configured to focus the electromagnetic radiation in the radiation-sensitive zones, the optical element comprising a zone plate having structures with sizes on an order of magnitude of a wavelength of the electromagnetic radiation, and wherein the radiation-sensitive zones are at varying distances from the optical element such that radiation-sensitive zones configured to detect shorter wavelengths of the electromagnetic radiation are at greater distances from the optical element compared to radiation-sensitive zones configured to detect longer wavelengths of the electromagnetic radiation, wherein the radiation-sensitive zones are in corresponding focal planes of the zone plate for corresponding colors, wherein the radiation sensitive zones comprise: a first radiation-sensitive zone in a focal plane of the zone plate for wavelengths associated with red visible light; a second radiation-sensitive zone in a focal plane of the zone plate for wavelengths associated with green visible light; and a third radiation-sensitive zone in a focal plane of the zone plate for wavelengths associated with blue visible light.
