Abstract

The spin of light in subwavelength-diameter waveguides can be orthogonal to the propagation direction of the photons because of the strong transverse confinement. This transverse spin changes sign when the direction of propagation is reversed. Using this effect, we demonstrate the directional spontaneous emission of photons by laser-trapped caesium atoms into an optical nanofibre and control their propagation direction by the excited state of the atomic emitters. In particular, we tune the spontaneous emission into the counter-propagating guided modes from symmetric to strongly asymmetric, where more than "Equation missing"% of the optical power is launched into one or the other direction. We expect our results to have important implications for research in quantum nanophotonics and for implementations of integrated optical signal processing in the quantum regime.

  • Two fundamental concepts underpin the SOI of light: optical angular momentum and geometric (Berry) phases for light.

    “Two important fundamental concepts underpin the SOI of light: optical angular momentum 57- 59 and geometric (Berry) phases for light 60- 62 .”

    From Spin–orbit interactions of light (2015) · cites this paper as [62]

    The Results section, “Spin–orbit coupling of light in an optical nanofibre” (page not provided), describes coupling between light’s spin and orbital angular momentum, supporting the optical-angular-momentum part of the claim. Our copy does not discuss geometric or Berry phases, so it does not support that part. (LLM, conf=0.85)

  • Geometric phases in optics originate from the coupling between intrinsic angular momentum and rotations of coordinates.

    “Geometric phases in optics originate from the coupling between intrinsic angular momentum and rotations of coordinates .”

    From Spin–orbit interactions of light (2015) · cites this paper as [62]

    The Results section, “Spin–orbit coupling of light in an optical nanofibre” (page unavailable), discusses coupling between light’s spin and orbital angular momentum and a position-dependent local spin. It does not address geometric phases or say that they originate from coupling intrinsic angular momentum to coordinate rotations. Searches for geometric phase, Berry phase, and coordinate rotations found no passage establishing that claim. (LLM, conf=0.74)

    Experimental — accuracy not yet measured
  • The Berry connection and Berry curvature immediately appear in all intrinsic SOI phenomena, such as the spin-Hall effect.

    “Therefore, the Berry connection and Berry curvature immediately appear in all intrinsic SOI phenomena, such as the spin-Hall effect.”

    From Spin–orbit interactions of light (2015) · cites this paper as [62]

    The Results section on spin–orbit coupling of light in an optical nanofibre describes transverse spin and directional emission. Searches for Berry connection, Berry curvature, and the spin-Hall effect found no passage linking those concepts or addressing the claim that Berry quantities appear in all intrinsic spin–orbit-interaction phenomena. Page numbers were unavailable in our copy. (LLM, conf=0.75)

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.
