Abstract

Engineering photon emission and scattering is central to modern photonics applications ranging from light harvesting to quantum-information processing. To this end, nanophotonic waveguides are well suited as they confine photons to a one-dimensional geometry and thereby increase the light-matter interaction. In a regular waveguide, a quantum emitter interacts equally with photons in either of the two propagation directions. This symmetry is violated in nanophotonic structures in which non-transversal local electric-field components imply that photon emission and scattering may become directional. Here we show that the helicity of the optical transition of a quantum emitter determines the direction of single-photon emission in a specially engineered photonic-crystal waveguide. We observe single-photon emission into the waveguide with a directionality that exceeds 90% under conditions in which practically all the emitted photons are coupled to the waveguide. The chiral light-matter interaction enables deterministic and highly directional photon emission for experimentally achievable on-chip non-reciprocal photonic elements. These may serve as key building blocks for single-photon optical diodes, transistors and deterministic quantum gates. Furthermore, chiral photonic circuits allow the dissipative preparation of entangled states of multiple emitters for experimentally achievable parameters, may lead to novel topological photon states and could be applied for directional steering of light.

  • The orbit-orbit coupling between IOAM and EOAM causes orbital-Hall effects: vortex-dependent shifts of optical beams.

    “Finally, the 'orbit-orbit coupling' between IOAM and EOAM 63,64 causes the orbital-Hall effects : vortex-dependent shifts of optical beams.”

    From Spin–orbit interactions of light (2015) · cites this paper as [64]

    The discussion on p. 2 explains directional photon emission through circular polarization and emitter–waveguide coupling, not coupling between intrinsic and extrinsic orbital angular momentum. Searches for IOAM, EOAM, orbital-Hall effects, and vortex-dependent beam shifts found no passage in our copy addressing the claim. (LLM, conf=0.76)

  • A similar interaction between the IOAM and EOAM occurs for vortex beams in inhomogeneous media, causing l-dependent transverse shifts at medium inhomogeneities (orbital-Hall effect).

    “A quite similar interaction between the IOAM and EOAM (vortex and trajectory) occurs for vortex beams in inhomogeneous media 18,64,90- 95 . In this case, beams experience  -dependent transverse shifts at the medium inhomogeneities.”

    From Spin–orbit interactions of light (2015) · cites this paper as [64]

    The discussion on p. 2 concerns helicity-dependent emission from quantum dots into a chiral waveguide, not vortex beams in inhomogeneous media. Searches for intrinsic and extrinsic orbital angular momentum and orbital-Hall transverse shifts found no passage addressing the attributed claim. (LLM, conf=0.77)

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.
