    Abstract: Provided is a polarization spectral filter, including: a first reflector and a second reflector disposed to face each other in a first direction; and a grating layer disposed between the first reflector and the second reflector. The grating layer includes a plurality of first grating elements and a plurality of second grating elements, the plurality of first grating elements and the plurality of second grating elements being alternately arranged in a second direction perpendicular to the first direction. The plurality of first grating elements include a first dielectric material having a first refractive index. The plurality of second grating elements include a second dielectric material having a second refractive index different from the first refractive index.

    Abstract: An optical filter includes pixels, each including: a first reflective plate configured to receive light and having first holes; and a second reflective plate facing the first reflective plate, separated from the first reflective plate by a gap, and having second holes corresponding to the first holes in shape and orientation. The second reflective plate is configured to transmit the light of a wavelength or the light of a range of wavelengths transmitted through the first reflective plate and incident on the second reflective plate, according to a spacing between adjacent holes of the first holes or a spacing between adjacent holes of the second holes. At least one pixel has the spacing between adjacent holes of the first holes different from that of at least one another pixel, or has the spacing between adjacent holes of the second holes different from that of the at least one another pixel.
