Abstract

We report the realization of tunable spin-dependent splitting in intrinsic photonic spin Hall effect. By breaking the rotational symmetry of a cylindrical vector beam, the intrinsic vortex phases that the two spin components of the vector beam carries, which is similar to the geometric Pancharatnam-Berry phase, are no longer continuous in the azimuthal direction, and leads to observation of spin accumulation at the opposite edge of the beam. Due to the inherent nature of the phase and independency of light-matter interaction, the observed photonic spin Hall effect is intrinsic. Modulating the topological charge of the vector beam, the spin-dependent splitting can be enhanced and the direction of spin accumulation is switchable. Our findings may provide a possible route for generation and manipulation of spin-polarized photons, and enables spin-based photonics applications.

  • A paraxial beam propagating in an optical fiber or along the optical axis of a uniaxial anisotropic crystal undergoes spin-to-vortex conversion.

    “(iii) A similar spin-to-vortex conversion occurs when a paraxial (collimated) beam propagates in an optical fiber 34 or along the optical axis of a uniaxial anisotropic crystal 35,36 .”

    From Spin–orbit interactions of light (2015) · cites this paper as [36]

    The paper describes a cylindrical vector beam whose circularly polarized components already carry opposite vortex phases (p. 2), and studies their spin-dependent splitting after part of the beam is blocked (pp. 1–3). Searches for optical-fiber propagation and propagation along a uniaxial crystal’s optical axis found no passage addressing spin-to-vortex conversion in either setting. (LLM, conf=0.76)

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.
