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.","lang":"eng"}],"language":[{"iso":"eng"}],"doi":"10.1364/optcon.569959","title":"TFLN channel waveguides of rib and strip type: Properties of guided modes","year":"2025","publication_identifier":{"issn":["2770-0208"]},"author":[{"id":"48077","full_name":"Hammer, Manfred","last_name":"Hammer","first_name":"Manfred","orcid":"0000-0002-6331-9348"},{"last_name":"Khan","first_name":"Shahriar","full_name":"Khan, Shahriar"},{"full_name":"Taheri, Behnood","first_name":"Behnood","last_name":"Taheri"},{"id":"53444","full_name":"Farheen, Henna","first_name":"Henna","last_name":"Farheen","orcid":"0000-0001-7730-3489"},{"id":"158","full_name":"Förstner, Jens","orcid":"0000-0001-7059-9862","first_name":"Jens","last_name":"Förstner"}],"date_updated":"2025-10-05T11:52:55Z","publication_status":"published","intvolume":"         4","file_date_updated":"2025-10-05T11:48:25Z","citation":{"mla":"Hammer, Manfred, et al. “TFLN Channel Waveguides of Rib and Strip Type: Properties of Guided Modes.” <i>Optics Continuum</i>, vol. 4, no. 10, Optica Publishing Group, 2025, p. 2356, doi:<a href=\"https://doi.org/10.1364/optcon.569959\">10.1364/optcon.569959</a>.","bibtex":"@article{Hammer_Khan_Taheri_Farheen_Förstner_2025, title={TFLN channel waveguides of rib and strip type: Properties of guided modes}, volume={4}, DOI={<a href=\"https://doi.org/10.1364/optcon.569959\">10.1364/optcon.569959</a>}, number={10}, journal={Optics Continuum}, publisher={Optica Publishing Group}, author={Hammer, Manfred and Khan, Shahriar and Taheri, Behnood and Farheen, Henna and Förstner, Jens}, year={2025}, pages={2356} }","ama":"Hammer M, Khan S, Taheri B, Farheen H, Förstner J.
