1. A polarizing filter comprising:
a wire grid comprising multiple wire elements, each wire element being spaced from an adjacent wire element and extending across the polarizing filter along a longitudinal axis of the wire element; and
an array of phase-modulating nanostructures formed on the wire grid, the array of phase-modulating nanostructures changing a phase of incident light a predetermined amount of phase change, each phase-modulating nanostructure being located in the array with respect to a corresponding wire element and in alignment with other phase-modulating nanostructures along the longitudinal axis of the corresponding wire element, each phase-modulating nanostructure comprising a square or a rectangular shape, a first width and a second width, the first width being perpendicular to the second width, and the first width and the second width of each phase-modulating nanostructure varying with respect to the first width and the second width of other phase-modulating nanostructures of the array based on a location of the phase-modulating nanostructure in the array.
