Abstract: An optical component comprises a metasurface comprising nanoscale elements. The metasurface is configured to receive incident light and to generate optical outputs. The geometries and/or orientations of the nanoscale elements provide a first optical output upon receiving a polarized incident light with a first polarization, and provide a second optical output upon receiving a polarized incident light with a second polarization that is different from the first polarization.

Abstract: The present disclosure provides an optical component, which may be a metasurface grating, including (a) a substrate; and (b) an array of subwavelength-spaced phase-shifting elements, which are tessellated on the substrate to produce, when illuminated with a polarized incident light, a diffracted light beam with a distinct polarization state for each of a finite number of diffraction orders, wherein the finite number is 2 or more.

Abstract: An attachment for an intensity-only sensor in an imaging device includes a polarization-sensitive diffraction grating. The polarization-sensitive diffraction grating is configured to receive incident light from a scene, and to modify the incident light to simultaneously produce a plurality of non-overlapping images of the scene, each of a different diffraction order, on the intensity-only sensor to facilitate full-Stokes imaging polarimetry. The attachment includes a first adjustment mechanism configured to control at least one of: vignetting of the plurality of non-overlapping images on the intensity-only sensor, or an object distance of the imaging device.

Abstract: An optical component can include a substrate. The optical component can include a metasurface disposed on the substrate. The metasurface can include one or more linearly birefringent elements. A spatially-varying Jones matrix and a far-field of the metasurface can define a transfer function of the metasurface configured to generate a controlled response in the far-field according to polarization of light incident on the metasurface.

Abstract: An optical component includes a substrate and a metasurface comprising one or more linearly birefringent elements. The linearly birefringent elements define a grating configured to implement parallel polarization analysis for a plurality of polarization orders for incident light of an arbitrary polarization.

Abstract: An optical device comprises a metasurface including a plurality of nanostructures. The nanostructures convert an input light of an arbitrary spin state into an output light of an arbitrary total angular momentum state characterized by a superposition of two independent orbital angular momentum (OAM) states.
