Abstract:
An ultra-thin planar device is used for arbitrary waveform formation on a micrometer scale, regardless of the incident light's polarization. Patterned perforations are made in a 30 nm-thick metal film, creating discrete phase shifts and forming a desired wavefront of cross-polarized, scattered light. The signal-to-noise ratio of these devices is at least one order of magnitude higher than current metallic nano-antenna designs. The focal length of a lens built on such principle can also be adjusted by changing the wavelength of the incident light. All proposed embodiments can be embedded, for example, on a chip or at the end of an optical fiber.

Claim (Index 14):
A method of making a planar plasmonic device, wherein the method comprises:\n forming a plurality of nanovoids perforated in a subwavelength-thick film, wherein said nanovoids form a pattern, and wherein a shape of each nanovoid provides a change of phase and magnitude of an incoming radiation due to plasmonic resonance of the radiation coupled to this nanovoid, wherein the shape of each nanovoid is configured to provide individual resonance characteristics, wherein the shape of the each nanovoid of the plurality of nanovoids is configured to provide a given phase front of outcoming radiation which is combined from portions of radiation exiting all nanovoids in said film.
