Light-controlled photon tunneling
Abstract
Recent measurements of photon tunneling through individual subwavelength pinholes in a gold film covered with a layer of polydiacetylene [Phys. Rev. Lett. 88, 187402 (2002)] has provided strong indication of "photon blockade" effects similar to Coulomb blockade phenomena observed in single-electron tunneling experiments. Here we report the observation of photon tunneling being blocked (gated) by light at a different wavelength. This suggests the possibility of building a class of "gated" photon tunneling devices for all-optical signal processing.
