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 photosensitivea‐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.
