Photo‐modulation of light up‐conversion was successfully demonstrated in a new type of light transducer using a high‐gain photoresponsive amorphous silicon carbide (a‐SiC:H) combined with an organic electroluminescent (EL) diode. Green EL output up‐converted from red input‐light was reversibly photo‐modulated by the simultaneously irradiated ultraviolet light due to the effective suppression of photocurrent multiplication in a‐SiC:H film. The present device can be applicable to the logic device for two‐dimensional optical computing.
