Abstract

We report on a direct experimental observation of dynamic localization (DL) of light in sinusoidally-curved lithium-niobate waveguide arrays which provides the optical analog of DL for electrons in periodic potentials subjected to ac electric fields as originally proposed by Dunlap and Kenkre [Phys. Rev. B 34, 3625 (1986)10.1103/PhysRevB.34.3625]. The theoretical condition for DL in a sinusoidal field is experimentally demonstrated.

  • Optical waveguide axis bending introduces an equivalent gravitational potential for photons.

    “In other words, optical waveguide axis bending introduces an equivalent gravitational potential for photons, which has found several applications, for example in dynamical localization of light [36, 37], control of photon tunneling [38] and realization of synthetic gauge fields for photons [39, 40] (for a recent review see [41]).”

    From Equivalence principle and quantum mechanics: quantum simulation with entangled photons (2018) · cites this paper as [36]

    The paper (p. 1) says waveguide curvature provides the optical equivalent of an applied electric field and relates the resulting force to axis bending. It reports dynamic localization of light in curved arrays (p. 4), supporting the cited example, but does not describe the effect as a gravitational potential for photons. (LLM, conf=0.84)

  • Photonic structures allow simulation of such external potentials in curved waveguide arrays and resolution of the evolution dynamics.

    “photonic structures provide the possibility of simulating such external potentials in curved waveguide arrays as well as of resolving the evolution dynamics [33,47,48].”
  • After every full period, an effective coupling constant c_eff = c J0(2πωA0/z0) can be defined.

    “One can formally show [25,33,47] that after every full period z → z + z 0 , an effective coupling constant”
  • Control over the sign can be acquired by dynamical modulation of the lattice, Raman-assisted tunneling or embedding defects in infinite arrays.

    “Control over this sign can be acquired by dynamical modulation of the lattice [16-21], Raman-assisted tunneling [22, 23] or embedding defects in infinite arrays [24].”

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.
