    摘要： A sub-wavelength grating device having controlled phase response includes a grating layer having line widths, line thicknesses, line periods, and line spacings selected to produce a first level of control in phase changes of different portions of a beam of light reflected from the grating layer. The device also includes a substrate affixed to the grating layer that produces a second level of control in phase changes of different portions of a beam of light reflected from the grating layer, the second level of control being accomplished abrupt stepping of the substrate in a horizontal dimension, ramping the substrate in a horizontal dimension, or changing the index of refraction in a horizontal dimension.

    摘要： Various embodiments of the present invention are directed to negative refractive index-based holograms that can be electronically controlled and dynamically reconfigured to generate one or more color three-dimensional holographic images. In one aspect, a hologram comprises a phase-control layer having a plurality of phase modulation elements. The phase-modulation elements are configured with a negative effective refractive index and selectively transmit wavelengths associated with one of three primary color wavelength. The hologram also includes an intensity-control layer including a plurality of intensity-control elements. One or more color three-dimensional images can be produced by electronically addressing the phase-modulation elements and intensity-control elements in order to phase shift and control the intensity of light transmitted through the hologram. A method for generating a color holographic image using the hologram is also provided, as is a system for generating a color holographic image.

    摘要： Various embodiments of the present invention are directed to dynamically and electronically reconfigurable optical devices that can be operated as a lens or prism for incident beams of electromagnetic radiation. The optical devices include a phase-modulation layer (1501) disposed between first and second nanowire layers (1502,1503). Overlapping nanowires can be electronically addressed to implement a selected effective refractive index pattern of one or more regions (1510) of the phase-modulation layer, such that each region refracts a portion of an incident beam of electromagnetic radiation having a wavelength of interest in order to focus, diverge, or bend the incident beam.

    摘要： Various embodiments of the present invention are directed to systems and methods for obtaining images of objects with higher resolution than the diffraction limit. In one aspect, a method for collecting evanescent waves scattered from an object comprises electronically configuring a reconfigurable device to operate as a grating for one or more lattice periods using a computing device. Propagating waves scattered from the object pass through the reconfigurable device and a portion of evanescent waves scattered from the object are projected into the far field of the object. The method includes detecting propagating waves and detecting the portion of evanescent waves projected into the far field for each lattice period using an imaging system.
