  bibo_abstract:
  - Samples of dielectric optical waveguides of rib or strip type in thin-film lithium
    niobate (TFLN) technology are characterized with respect to their optical loss
    using the Fabry-Pérot method. Attributing the losses mainly to sidewall roughness,
    we employ a simple perturbational procedure, based on rigorously computed mode
    profiles of idealized channels, to estimate the attenuation for waveguides with
    different cross sections. A single fit parameter suffices for an adequate modelling
    of the effect of the waveguide geometry on the loss levels.@eng
