摘要

Photomixing detector comprises a photo-sensitive substrate (1) and is illuminated from the rear side of the substrate. An independent claim is also included for a method for operating a photo mixing detector. Preferred Features: The substrate is 0.5-100 mu m, preferably 1-50 mu m, especially 2-20 mu m thick. The substrate is doped so that the electrical fields applied to the connection or structure have a penetration depth of more than the whole thickness of the substrate. The detector has a photodiode structure with a p-n junction, pin diode and Schottky contact.
