    摘要： Materials and methods for fabricating and using negative index materials are disclosed. A negative index material comprises a three-dimensional volume including a bulk solution and a plurality of unit cells disposed in the bulk solution in a substantially random pattern. Each unit cell comprises a periodic hole array pattern on a substrate or a resonator formed on a first surface of a substrate, and a thin wire pattern formed on a second surface of the substrate. The combination of the unit cells in the bulk solution produces a negative effective permeability and a negative effective permittivity over a frequency band of interest for the three-dimensional volume. The negative index material may be used to focus radiation by directing an incident radiation at the negative index material and generating a focused radiation by a negative refraction of the incident radiation in the negative index material.

    摘要： A structure includes a film having a plurality of nanoapertures and a semiconductor layer in connection with the film. The nanoapertures are configured to allow the transmission of a predetermined subwavelength of light through the film via the plurality of nanoapertures. The semiconductor layer facilitates the modulation of the predetermined subwavelength of light transmitted through the film. The structure also includes a carrier generator for modulating the predetermined subwavelength of light by generating charge carriers.

    摘要： A deformable optical element includes an elastically deformable lens. Electrical contacts are directly attached to the elastically deformable lens and configured to receive an applied voltage. The electrical contacts have opposing surfaces configured to develop electrostatic forces in response to the applied voltage. The electrostatic forces deform the elastically deformable lens to create a predetermined optical effect.

    摘要： Apparatuses and methods for modulating electromagnetic radiation are disclosed. A plasmon waveguide including an array of metallic nanoparticles disposed on a dielectric substrate is provided. The plasmon waveguide is disposed on a MEMS structure. An electromagnetic radiation signal is applied to a tapered fiber disposed proximate the MEMS structure. The intensity of the electromagnetic radiation signal passing through the tapered fiber is modified by displacing a deformable member of the MEMS structure to modify a distance between the plasmon waveguide and the tapered fiber such that an evanescent field of the tapered fiber causes a plasmon resonance in the plasmon waveguide.

    摘要： Various embodiments of the present invention are directed to nanowire-based photodetectors that can be used to convert information encoded in a channel of electromagnetic radiation into a photocurrent encoding the same information. In one embodiment of the present invention, a photodetector comprises a waveguide configured to transmit one or more channels of electromagnetic radiation. The photodetector includes a first terminal and a second terminal. The first terminal and the second terminal are positioned on opposite sides of the waveguide. The photodetector also includes a number of nanowires. Each nanowire interconnects the first terminal to the second terminal and a portion of each nanowire is embedded in the waveguide.
