    摘要: Dynamically reconfigurable holograms with electronically erasable programmable intermediate layers are disclosed. An example apparatus includes first nanowires, each of the first nanowires having protuberances along a length thereof. The example apparatus also includes second nanowires arranged approximately perpendicular to the first nanowires, the protuberances of the first nanowires being approximately parallel to corresponding ones of the second nanowires. In addition, a layer is disposed between the first and second nanowires. The layer is to control refractive indices at nanowire intersections at intersecting ones of the first and second nanowires.

    摘要: Various embodiments of the present invention relate to systems that can be used as holograms and can be electronically controlled and dynamically reconfigured to generate three-dimensional motion picture images. In one embodiment, a dynamically reconfigurable hologram (1200) comprises a phase-control layer (1202) including a two-dimensional array of phase-modulation pixels (1212). The hologram also comprises an intensity-control layer (1204) including a two-dimensional array of intensity-control pixels (1214). One or more three-dimensional motion pictures can be produced by electronically addressing the individual phase-modulation pixels and intensity-control pixels in order to phase and control the intensity of light emanating from pixels of the hologram.

    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.

    摘要: A nano-colonnade structure-and methods of fabrication and interconnection thereof utilize a nanowire column grown nearly vertically from a (111) horizontal surface of a semiconductor layer to another horizontal surface of another layer to connect the layers. The nano-colonnade structure includes a first layer having the (111) horizontal surface; a second layer having the other horizontal surface; an insulator support between the first layer and the second layer that separates the first layer from the second layer. A portion of the second layer overhangs the insulator support, such that the horizontal surface of the overhanging portion is spaced from and faces the (111) horizontal surface of the first layer. The structure further includes a nanowire column extending nearly vertically from the (111) horizontal surface to the facing horizontal surface, such that the nanowire column connects the first layer to the second layer.
