  bibo_abstract:
  - Straight dielectric waveguide channels made from slabs of thin-film lithium niobate
    (TFLN), or lithium niobate on insulator (LNOI), are investigated in the linear
    regime, for channels of rib and strip type with common trapezoidal cross sections,
    in Z-cut and X-cut samples at varying on-chip orientation. We clarify the theoretical
    basis for the waveguides with potentially non-diagonal core permittivity. Symmetry
    classes can be distinguished that differ in their consequences for potential modal
    degeneracy and polarization conversion. Our rigorous numerical analysis by means
    of a finite-element solver takes the anisotropy of the lithium niobate cores rigorously
    into account. We discuss extensive data for effective indices, polarization properties,
    and hybridization of guided modes, in single- and multimode channels. Scans over
    the waveguide width and orientation as primary parameters are complemented by
    a series of illustrations of vectorial mode profiles. These turn out to be essentially
    complex in cases of X-cut channels at non-crystal-axis-aligned orientations.@eng
