Spatially addressable light transducer using an organic electroluminescent diode combined with amorphous silicon carbide film as an electron photoinjecting electrode

Abstract
A new type of light transducer has been designed consisting of an organic electroluminescent (EL) diode on a photoconductive amorphous silicon carbide (a-SiC:H) film as an electron photoinjecting electrode. Input light received by a photosensitive a-SiC:H film is transduced to the output light with a different wavelength emitted from an EL diode in the layered configuration. The input-light pattern was well kept spatially in the output. The EL output light was controllable with dc voltage applied to the device and input-light intensity. These features are suggested to be potentially applicable for a new type of the spatial light modulator.
