Abstract: An optical device that includes a metal film defining an aperture through the metal film, a plurality of first concentric ridges formed around the aperture on a first side of the metal film. Each pair of adjacent first concentric ridges are spaced apart by a first period, p1, and each pair of adjacent ones of the plurality of second concentric ridges are spaced apart by a second period, p2. In at least some instances, n1p1 is within 10% of n2p2, where n1 is an index of refraction of the material adjacent the first side of the metal film and n2 is an index of refraction of the material adjacent the second side of the metal film. The optical device optionally includes a plurality of apertures. In some instances, two or more, or even all, of the apertures have a plurality of concentric ridges formed around each of those apertures. In some instances, the metal film may be used as a polarizer or wavelength filter.

Abstract: A solar cell arrangement includes a metal layer defining multiple cavities through the metal layer. Each cavity has a lateral cross-sectional dimension that is preferably in the range of 50 nanometers to 5 micrometers. The solar cell arrangement may include sets of solar cell elements, each set including cavities with one or more dimensions (e.g., lateral cross-sectional dimension or dimensions) that differ from those of cavities in the other sets. It is believed that each set of solar cell elements channels light of a different wavelength band into its cavities utilizing surface plasmon modes on the walls of the cavities or optical cavity modes within the cavity (or both surface plasmon modes and optical cavity modes). A solar cell is disposed in each of the cavities. Preferably, the solar cell is selected to absorb light in the wavelength hand associated with the corresponding cavity and to convert the absorbed light into electricity.
