Abstract

We study the polarization properties of elliptical femtosecond-laser-written waveguide arrays. An analytical model is presented to explain the asymmetry of the spatial transverse profiles of linearly polarized modes in these waveguides. This asymmetry produces a polarization-dependent coupling coefficient, between adjacent waveguides, which strongly affects the propagation of light in a lattice. Our analysis explains how this effect can be exploited to tune the final intensity distribution of light propagated through the array and links the properties of a polarizing beam splitter in integrated optical circuits to the geometry of the waveguides.

  • The ellipticity of the waveguide modes contributes to slightly different refractive indices for H and V (Δn ≈ 10−5).

    “This ellipticity is due to the intensity distribution of the writing laser beam waist and contributes to slightly different refractive indices for H and V (Δn ≈ 10 -5 ).40”

    From Integrated-optics heralded controlled-NOT gate for polarization-encoded qubits (2018) · cites this paper as [40]

    Section II (page not specified in our copy) describes different H and V mode profiles in elliptical waveguides. Section III reports a refractive-index contrast of 9.37 × 10⁻⁴ between core and cladding, not an H–V index difference. Our copy does not establish the claimed Δn ≈ 10⁻⁵ or attribute the ellipticity to the writing beam waist. (LLM, conf=0.84)

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.
