Abstract
An image sensor includes polarizing filters and spectral filters that provide on-chip simultaneous full Stokes polarization parameters (both linear and circular polarization) and multi/hyper spectral imaging. A polarizing filter polarizes incident light into a predetermined linear direction. The light-polarizing filter includes a wire grid and an array of phase-modulating nanostructures. The wire grid includes at least one wire that includes a series of metal-insulator-metal wire structures. The array of phase-modulating nanostructures is formed on the wire grid and changes a phase of the incident light a predetermined amount. A phase-modulating nanostructure is a high-dielectric-index nanostructure that changes of incident light based on a first width and a second width of the phase-modulating nanostructure in which the first width is perpendicular to the second width.
