    摘要: An apparatus includes at least one conductive layer, an electromagnetic (EM) wave source, and an electron source. The conductive layer has a thickness less than 5 nm. The electromagnetic (EM) wave source is in electromagnetic communication with the at least one conductive layer and transmits a first EM wave at a first wavelength in the at least one conductive layer so as to generate a surface plasmon polariton (SPP) field near a surface of the at least one conductive layer. The electron source propagates an electron beam at least partially in the SPP field so as to generate a second EM wave at a second wavelength less than the first wavelength.

    摘要: An optical device is provided having a solid state nonlinear material with a nanostructured extent, in at least one dimension, that is less than about 10 nm or that is at a temperature of less than about 77 K. An electronic band gap, EGap, of the material is at least about twice as large as an energy of a photon with a wavelength, λ, equal to an operational wavelength of the device. The material is characterized by a switching figure of merit, ξ, having a value that is at least about 2π. A dielectric structure is around at least one dimension of the nonlinear material in a geometric arrangement having a characteristic photonic band gap that at least partially overlaps the electronic band gap of the material. At least one waveguide is disposed at the dielectric structure in sufficient proximity with the material for coupling light to the material.

    摘要: A solar cell includes a photovoltaic material region. The photovoltaic material region is covered by a uniform anti-reflection coating. A photonic crystal structure is positioned on the photovoltaic material region. The photonic crystal structure provides a medium to produce a plurality of spatial orientations of an incident light signal received by the solar cell so as to allow trapping of a selective frequency of incident light in the solar cell.
