Abstract
We present a new photodetector based on the synchronous drift of photogenerated carriers with a moving interference pattern [1-3]. The proposed resonant photodetector is a semiconductor with injecting contacts, used as a high level heterodyne mixer. It detects the beating signal between two laser beams at different frequencies and provides a large detection volume which could be suitable for the efficient optical generation of microwave signals [4].
