Photonic Spin Hall Effect at Metasurfaces

Abstract

The spin Hall effect (SHE) of light is very weak because of the extremely small photon momentum and spin-orbit interaction. Here, we report a strong photonic SHE resulting in a measured large splitting of polarized light at metasurfaces. The rapidly varying phase discontinuities along a metasurface, breaking the axial symmetry of the system, enable the direct observation of large transverse motion of circularly polarized light, even at normal incidence. The strong spin-orbit interaction deviates the polarized light from the trajectory prescribed by the ordinary Fermat principle. Such a strong and broadband photonic SHE may provide a route for exploiting the spin and orbit angular momentum of light for information processing and communication.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • For nonparaxial beams, the simple association of SAM and IOAM with polarization and vortex is not valid; the SAM and IOAM become (3), and the total intrinsic AM is preserved, so part of the SAM is transferred to the IOAM (spin-to-orbital AM conversion).

    “For nonparaxial beams, consisting of circularly-polarized plane waves with the wavevectors forming a cone with an opening angle θ (like in Fig. B2b), the SAM and IOAM become 8,27,96- 98”

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.
