Abstract

An organic multi-layered optical logic device for two-dimensional optical computing which can perform ‘NOT’ operation, was successfully demonstrated in the light transducer composed of a high-gain organic photoresponsive heterojunction between copper phthalocyanine (CuPc) and perylene pigment (Me-PTC) layers and an organic electroluminescent (EL) diode. EL output by the irradiation of red light exciting CuPc was effectively erased upon the superimposed irradiation of blue light exciting Me-PTC because of the effective suppression of multiplied photo-current reaching 104-fold at the CuPc/Me-PTC heterojunction. When a spatial pattern image was used for the superimposed blue light, EL output was erased as patterned with a high spatial resolution smaller than 280 μm.
