Optical “NOT” Operation in an Organic Film Device Combining OLED and Current Photo-controllable Organic Film
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.

For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.
Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
