Organic optical image processor
The all-organic optical image processor was fabricated combining an organic electroluminescent (EL) layer with photocurrent multiplication layer. In this device, input light image from one side is once converted to a large photocurrent, which is fed to an EL layer emitting output light image from the other side with keeping the image pattern. The photocurrent multiplication in pigment-dispersed polymer films enabled us to fabricate a large area device suitable for image processors. The optical operation was realized by designing the output-input light intensity characteristics in this device. We demonstrated two types of optical image processing, "AND" and "OR", for two input images.
