    摘要: A patterned array of metallic nanostructures and fabrication thereof is described. A device comprises a patterned array of metallic columns vertically extending from a substrate. Each metallic column is formed by metallically coating one of an array of non-metallic nanowires catalytically grown from the substrate upon a predetermined lateral pattern of seed points placed thereon according to a nanoimprinting process. An apparatus for fabricating a patterned array of metallic nanostructures is also described.

    摘要: A patterned array of metallic nanostructures and fabrication thereof is described. A plurality of nanowires is grown on a substrate, the plurality of nanowires being laterally arranged on the substrate in a predetermined array pattern. The plurality of nanowires is coated with a metal to generate a plurality of metal-coated nanowires. Vacancies between the metal-coated nanowires are filled in with a sacrificial material for stabilization, and the metal-coated nanowires are planarized. The sacrificial material is removed, the patterned array of metallic nanostructures being formed by the plurality of planarized metal-coated nanowires.

    摘要: An apparatus for sensing at least one property of a fluid is described. A first photonic crystal structure and a second photonic crystal structure are defined in a dielectric slab. The first and second photonic crystal structures comprise differently patterned arrays of channels extending through the dielectric slab. The apparatus further comprises a fluid introduction device configured to introduce a common volume of the fluid into the channels of the first and second photonic crystal structures. The at least one property of the fluid can be sensed by measuring the propagation of radiation through the first and second photonic crystal structures.

    摘要: Various embodiments of the present invention relate to dynamically reconfigurable hologram comprising a phase-modulation layer and an intensity-control layer. The phase modulation layer comprises an electronically programmable erasable negative index material crossbar. The crossbar includes a first layer of approximately parallel nanowires (502) and a second layer of approximately parallel nanowires (504) that overlay the nanowires in the first layer. The nanowires in the first and second layers have substantially regularly spaced fingers. The crossbar also includes resonant elements (812) comprising two fingers of a nanowire in the first layer, two fingers of a nanowire in the second layer, and an intermediate layer (1006,1302) sandwiched between the nanowire in the first layer and the nanowire in the second layer. The refractive index of each resonant element is controlled by changing the charge density within the intermediate layer.
