Photonic Spin Hall Effect with Nearly 100% Efficiency

Luo, Weijie, Xiao, Shiyi, He, Qiong, Sun, Shulin, Zhou, Lei·2015·Advanced Optical Materials

Abstract

Photonic spin Hall effect (PSHE; i.e., spin‐polarized photons can be laterally separated in transportation) gains increasing attention from both science and technology, but available mechanisms either require bulky systems or exhibit very low efficiencies. Here it is demonstrated that a giant PSHE with ≈100% efficiency can be realized at certain meta‐surfaces with deep‐subwavelength thicknesses. Based on rigorous Jones matrix analysis, a general criterion to design meta‐surfaces that can realize 100%‐efficiency PSHE is established. The criterion is approachable from two distinct routes at general frequencies. As a demonstration, two microwave meta‐surfaces are fabricated and then experimentally characterized, both showing ≈90% efficiencies for the PSHE. The findings here pave the way for many exciting applications based on high‐efficiency manipulations of photon spins, with a polarization detector experimentally demonstrated here as an example.

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.
