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."}],"date_created":"2025-08-06T09:36:30Z","file":[{"date_created":"2025-10-05T11:48:25Z","creator":"fossie","success":1,"content_type":"application/pdf","file_id":"61516","date_updated":"2025-10-05T11:48:25Z","relation":"main_file","access_level":"closed","file_size":5417636,"file_name":"2025-08 Hammer - Optics Continuum - TFLN channel waveguides of rib and strip type.
