Metasurface for characterization of the polarization state of light
Open accessAbstract
The miniaturization of measurement systems currently used to characterize the polarization state of light is limited by the bulky optical components used such as polarizers and waveplates. We propose and experimentally demonstrate a simple and compact approach to measure the ellipticity and handedness of the polarized light using an ultrathin (40 nm) gradient metasurface. A completely polarized light beam is decomposed into a left circularly polarized beam and a right circularly polarized beam, which are steered in two directions by the metasurface consisting of nanorods with spatially varying orientations. By measuring the intensities of the refracted light spots, the ellipticity and handedness of various incident polarization states are characterized at a range of wavelengths and used to determine the polarization information of the incident beam. To fully characterize the polarization state of light, an extra polarizer can be used to measure the polarization azimuth angle of the incident light.

By combining a metalstripe metasurface with a linear polarizer and performing two successive measurements, or by Fourier transforming the transmitted near-field when a quarter-wave plate is placed in front of the metasurface, it is possible to determine the Stokes parameters.
“For example, by combining the metasurface with a linear polarizer and performing two successive measurements[11, 14] or, alternatively, by Fourier transforming the transmitted near-field when a quater-wave plate is placed in front of the metasurface [12], it is possible to determine the Stokes parameters.”

Transmission through a space-variant metalstripe metasurface results in part of the incident light being redirected (diffracted), similar to blazed gratings.
“Particularly, early work has considered transmission through a space-variant metalstripe metasurface[11, 12], which results in part of the incident light being redirected (i.e., diffracted), similar to the functionality of blazed gratings[13].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
