Patent ID: 7361883

Claim:
Photonic mixer device for receiving incident electromagnetic radiation includes a photosensitive layer ( 105 ) responsive to the incident electromagnetic radiation, at least two modulation gates ( 3 , 4 , 103 , 104 , 203 , 204 , 303 , 304 , 403 , 404 ) and at least two readout electrodes ( 1 , 2 , 101 , 102 , 201 , 202 , 301 , 302 , 401 , 402 , 501 , 502 , 601 , 602 ) connected to the photosensitive layer, the modulation gates ( 3 , 4 , 103 , 104 , 203 , 204 , 303 , 304 , 403 , 404 ) being able to be connected to a modulation device which raises and lowers the potential of the modulation gates relative to one another and relative to a constant potential of the readout electrodes corresponding to a desired modulation function, characterized in that the readout electrodes ( 1 , 2 , 101 , 102 , 201 , 202 , 301 , 302 , 401 , 402 , 501 , 502 , 601 , 602 ) each have at least two discrete electrode sections ( 1 A- 1 E, 2 A- 2 E) arranged at a distance alongside each other, characterized in that at least two memory gates ( 323 , 324 ) are provided which surround the readout electrodes ( 301 , 302 ).
