    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.

    Abstract: According to the invention, there is provided a circular polarizing filter for selectively transmitting circularly polarized light of any one sense of either right-handed circularly polarized light or left-handed circularly polarized light at a specific wavelength in which scattering transmittance/vertical transmittance when circularly polarized light of the sense of the specific wavelength enters from any one surface is less than scattering reflectance/regular reflectance when circularly polarized light of the other sense enters from the surface. The circular polarizing filter includes a circularly-polarized light separating layer, the circularly-polarized light separating layer includes a reflected light-scattering circularly-polarized light separating layer, and may further include a reflected light-non-scattering circularly-polarized light separating layer, the reflected light-scattering circularly-polarized light separating layer is composed of a layer having a cholesteric liquid crystalline phase fixed therein, and the reflected light-non-scattering circularly-polarized light separating layer is composed of a layer having a cholesteric liquid crystalline phase fixed therein, or a laminate including a linearly-polarized light separating layer and a λ/4 phase difference layer. The circular polarizing filter of the invention has a high circular polarizance, and a high-sensitivity sensor system can be provided using the circular polarizing filter of the invention.
