Patent ID: 6897436

Claim:
A system for optical processing based on light-controlled photon tunneling comprising: a prism having an upper surface; a metallic film layer deposited on said upper surface of said prism, said metallic film layer having at least one microscopic aperture formed therethrough; a non-linear optical film layer formed on said metallic film layer and covering said at least one microscopic aperture; an optical fiber tip positioned above said at least one microscopic aperture and adjacent said non-linear optical film layer; control means for selectively positioning and controlling movement of said optical fiber tip; a first light source for generating a first light beam, said first light beam being directed at said microscopic aperture; and, a second light source for generating a second light beam, said second light beam being directed at said microscopic aperture, said second light source being selectively actuated to selectively prevent photon tunneling of said first light beam through said microscopic aperture, wherein intensity of transmitted photons is detected by said optical fiber tip.
