A system ( 10 ) for optical processing based on light-controlled photon tunneling is provided. The system ( 10 ) includes a prism ( 12 ) having a metallic film layer ( 14 ) formed on an upper surface thereof. The metallic film layer ( 14 ) has a microscopic aperture ( 18 ) formed therethrough and the microscopic aperture ( 18 ) is covered by a layer of non-linear optical film. A first light beam ( 30 ) is projected towards aperture ( 18 ) and photons from first light beam ( 30 ) tunnel through aperture ( 18 ). A second light beam ( 32 ) is also projected towards microscopic aperture ( 18 ), with the second light beam ( 32 ) having a different wavelength than that of light beam ( 30 ). Selective actuation and modulation of light beam ( 32 ) allows for selective control over the rate and intensity of the photons which tunnel through microscopic aperture ( 18 ). The intensity of transmission of the photons from light beam ( 30 ) are measured by optical fiber tip ( 22 ), thus allowing for the creation of optical gates, switches, and other optical processing devices.
