    Abstract: A diffractive optical element (DOE) includes a substrate layer; and a nanostructure layer comprising nanostructures having a predetermined periodicity ranging from 0.75λ to 3λ of a target wavelength λ. The nanostructures are pillar-shaped nanostructures formed on a surface of the substrate layer, holes formed in the substrate layer, or a combination thereof. At least one nanostructure has a plan-view cross-sectional shape of a circle, an oval, a square, or a rectangle. The plan-view cross-sectional shape of at least one nanostructure includes a rounded corner having a corner radius selected based on a desired light dot nonuniformity of a diffraction pattern generated by the DOE. When the nanostructures are pillar-shaped, a refractive index of the nanostructures is greater than a refractive index of the substrate layer. When the nanostructures are holes, a refractive index of the nanostructures is less than a refractive index of the substrate layer.

    IPC: G02F1/29

    Abstract: A diffractive optical pattern generator includes a diffractive optical element layer, and a nanostructure layer configured for beam steering an input light applied to the diffractive optical pattern generator to at least one of a polar beam-steering angle that is measured in a plane that is substantially normal to a direction of the input light and an azimuth beam-steering angle measured with respect to the direction of the input light. A dynamic transmission layer may be included in which at least one region of the dynamic transmission layer may be selectively controllable to transmit light through or to block light from passing through the dynamic transmission layer. The nanostructure layer may include nanostructures having a periodicity ranging from 0.75 λ to 3 λ of a target wavelength λ. The nanostructure layer may be configured to beam steer light input to the DOE layer or beam steer light output from the DOE layer.

    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.
