A circular system of coupled waveguides and an optical analogue of bloch oscillations

Abstract

The process of light propagation in a nonuniform system of tunnel-coupled waveguides is studied. The nonuniform system of waveguides is realized by making a circular system of waveguides on the inner wall of a supporting tube with the help of the SPCVD technology, which is designed for the synthesis of preforms of optical fibers. It is shown that the waveguide light beam propagates in such a system along a wavelike trajectory and partially radiates outwards at the crests of this trajectory. The oscillation period of the trajectory is measured, and it is shown that it is possible to input radiation into the waveguide mode by the process that is inverse to the process of light emission from the structure.

Statistics

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The first experimental observation of Bloch oscillations in curved lattices was reported in 2004.

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.
