  • Publication number: 20110019189
    Abstract: A device for enhancing transmission of incident electromagnetic radiation at a predetermined wavelength is presented that includes an aperture array structure in a thin film. The structure includes a repealing unit cell having more than one aperture including a first aperture and a second aperture, wherein a parameter of the first aperture differs from that of the second aperture. The unit cell repeats with a periodicity on the order of or less than said predetermined wavelength, The structure parameters are configured to preferentially support cavity modes for coupling to and enhancing transmission of a predetermined polarization state at the predetermined wavelength. By structuring the unit cell with apertures that differ by appropriate degrees in at least one of dimension, height, dielectric constant of material filling the apertures, shape, and orientation, the devices can be adapted for polarization and/or wavelength filtering- and/or light circulating, weaving, or channeling.
