Abstract

We demonstrate nanoscale spin control of photons emitted by an atomic system coupled to a compact plasmonic nanoantenna supporting phase-locked interference of different multipolar moments within a single resonance. Experimentally we observe chiral light emission from quantum dots over split-ring resonant nanoantennas, where the spin of the emitted photons is locked to their transverse momentum. We demonstrate that the polarization can vary from linear to elliptical with ellipticity reaching ±0.5 for emission into opposite halves of the symmetry plane of the nanoantenna.

  • Properly designing anisotropic and inhomogeneous structures allows considerable enhancement of SOI effects and highly efficient spin-dependent shaping and control of light.

    “Moreover, properly designing anisotropic and inhomogeneous structures (e.g., metasurfaces or liquid crystals) allows considerable enhancement of the SOI effects and highly efficient spindependent shaping and control of light 37- 45 .”

  • The fundamental mechanisms underlying spin-dependent deformation of optical fields are geometric phases.

    “Most importantly, the fundamental mechanisms underlying the spin-dependent deformation of optical fields are geometric phases (see Box 2).”

  • For a planar anisotropic element (transparent retarder with phase δ and anisotropy axis at angle α), the Jones-matrix transformation of wave polarization becomes (5), with off-diagonal elements originating from geometric phases induced by rotation of coordinates.

    “Performing a rotation by the angle α to the laboratory coordinate frame and also writing this matrix in the helicity basis of right-hand and left-hand circular polarizations, the Jones-matrix transformation of the wave polarization becomes 5,6,37- 39,114”

  • The extrinsic spin-Hall effect generated by space-variant anisotropic elements allows complete spatial separation of the two spin states of light: linearly-polarized light with σ = 0 is transformed into two well-separated σ' = ±1 beams propagating in different directions.

    “This extrinsic spin-Hall effect generated by the space-variant anisotropic elements allows complete spatial separation of the two spin states of light: a linearly-polarized light with σ = 0 is transformed into two well-separated σ ′ = ± 1 beams propagating in different directions (Fig. 3b) 37 .”

  • The off-diagonal geometric-phase elements of Eq. (5) offer helicity-dependent manipulation of light using the orientation of the anisotropy axis; anisotropic subwavelength gratings with space-variant orientation have been employed for geometric-phase-induced shaping of light.

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.
