Abstract

We examine, both experimentally and theoretically, an interaction of tightly focused polarized light with a slit on a metal surface supporting plasmon-polariton modes. Remarkably, this simple system can be highly sensitive to the polarization of the incident light and offers a perfect quantum weak measurement tool with a built-in postselection in the plasmon-polariton mode. We observe the plasmonic spin Hall effect in both coordinate and momentum spaces which is interpreted as weak measurements of the helicity of light with real and imaginary weak values determined by the input polarization. Our experiment combines the advantages of (i) quantum weak measurements, (ii) near-field plasmonic systems, and (iii) high-numerical aperture microscopy in employing the spin-orbit interaction of light and probing light chirality.

  • Focusing circularly-polarized light by a high-numerical-aperture lens generates a spin-dependent optical vortex in the focal field.

    “(ii) Focusing of circularly-polarized light by a high-numerical-aperture lens results in the generation of a spin-dependent optical vortex (i.e., helical phase producing orbital angular momentum) in the focal field.”

    From Spin–orbit interactions of light (2015) · cites this paper as [20]

    The note on p. 5 states that high-NA focusing induces partial spin-to-orbital angular-momentum conversion, supporting the spin-dependent aspect of the claim. The discussion of the focused field on p. 3 does not establish that circularly polarized input generates a helical-phase optical vortex in the focal field. (LLM, conf=0.82)

  • This helicity-dependent switching of the central intensity was observed in experiments and employed for spin-controlled transmission of light via chiral nanoapertures and AM-induced circular dichroism in non-chiral structures.

    “This helicity-dependent switching of the central intensity was observed in experiments 20,25 and employed for spin-controlled transmission of light via chiral nanoapertures 104 and AM-induced circular dichroism in non-chiral structures 105 .”

    From Spin–orbit interactions of light (2015) · cites this paper as [20]

    Citation 105 is attached to the claim about angular-momentum-induced circular dichroism in non-chiral structures. The paper’s introduction (p. 1) discusses helicity-dependent beam shifts, and its conclusion (p. 5) reports a plasmonic spin Hall effect at a straight slit, but neither passage addresses that circular-dichroism claim. Searches for circular dichroism, non-chiral structures, and central-intensity switching found no supporting passage in our copy. (LLM, conf=0.75)

    Experimental — accuracy not yet measured

  • For vortex beams with l=1, the z-component of the field has vortex charge l+σ; for lσ=1 this component is a charge-2 vortex with vanishing intensity in the center, while for lσ=-1 it is a charge-0 vortex with maximum intensity in the center.

    “The most striking manifestation of this effect appears for vortex beams with  = 1, Fig. 2c. According to the transformation (4), the z -component of the field has the vortex charge  +σ . Therefore, for  σ = 1 this component represents a charge-2 vortex with vanishing intensity in the beam center, while for  σ = -1 this is a charge-0 vortex with maximum intensity in the center.”

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.
