A negative index material (or metamaterial) crossbar includes a first layer of approximately parallel nanowires and a second layer of approximately parallel nanowires that overlay the nanowires in the first layer. The nanowires in the first layer are approximately perpendicular in orientation to the nanowires in the second layer. Each nanowire of the first layer and each nanowire of the second layer has substantially regularly spaced fingers. The crossbar further includes resonant elements at nanowire intersections between the respective layers. Each resonant element includes two fingers of a nanowire in the first layer and two fingers of a nanowire in the second layer.

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.

A photonic device and a method of making the device employ a bramble layer of nanowires having an uneven contour. The photonic device and the method include a first layer of a microcrystalline material provided on a substrate surface and a bramble layer of nanowires formed on the first layer. The photonic device and the method further include a second layer provided on the bramble layer. The nanowires have first ends integral to crystallites in the microcrystalline first layer and second ends opposite to the first ends. Different angular orientations of the nanowires provide the uneven contour of the bramble layer. The second layer has an uneven surface corresponding to the uneven contour of the bramble layer.

A NERS-active structure includes a deformable, active nanoparticle support structure for supporting a first nanoparticle and a second nanoparticle that is disposed proximate the first nanoparticle. The nanoparticles each comprise a NERS-active material. The deformable, active nanoparticle support structure is configured to vary the distance between the first nanoparticle and the second nanoparticle while performing NERS. Various active nanoparticle support structures are disclosed. A NERS system includes such a NERS-active structure, a radiation source for generating radiation scatterable by an analyte located proximate the NERS-active structure, and a radiation detector for detecting Raman scattered radiation scattered by the analyte. A method for performing NERS includes providing such a NERS-active structure, providing an analyte at a location proximate the NERS-active structure, irradiating the NERS-active structure and the analyte with radiation, varying the distance between the nanoparticles, and detecting Raman scattered radiation scattered by the analyte.
