Abstract:
A solid-state optoelectronic shutter having an input face and an output face, comprising a semiconductor material, having formed therein or thereon:a planar photodiode, having a planar surface, and optically communicating with the input face; a planar LED layer, having a planar surface substantially parallel to the planar photodiode, and optically communicating with the output face; a planar gate layer, intermediate the planar photodiode and the planar LED which gates the flow of charge carriers between the photodiode and the LED; and first and second transparent, conductive coatings on the input and output faces, respectively, a control voltage source which applies a control voltage is applied between the first and second coatings to switch or modulate light generated at the output face.
