Quasi-incoherent propagation in waveguide arrays

Abstract

In this letter a “quasi-incoherent” propagation in waveguide arrays is theoretically derived and experimentally verified. Depending on the initial light distribution the propagation in a waveguide array after multiwaveguide excitation exhibits an interference pattern or not. For the experimental verification the waveguide array is realized in OH rich fused silica by femtosecond laser direct writing. The light propagation within the array is directly visible due to the fluorescence of the created color centers. A precise excitation of different waveguides is achieved using a phase grating.

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?

  • Fluorescence microscopy allows direct monitoring of the light intensity distribution inside the samples.

    “the light intensity distribution can be directly monitored inside the samples using a fluorescence microscopy technique [24,25].”

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.
