The fairly general arguments underlying the leakage suppression apply to TM modes of all orders simultaneously, and are independent of wavelength. These plus-shaped waveguides support strictly guided, non-leaky TM modes for, in principle, arbitrarily shallow etching."}],"ddc":["530"],"volume":41,"oa":"1","file":[{"file_size":920206,"relation":"main_file","file_name":"2024-08 Farheen - JOSA B - Symmetry-protected TM modes in rib-like, plus-shaped optical waveguides with shallow etching.pdf","content_type":"application/pdf","creator":"fossie","file_id":"55752","access_level":"local","date_updated":"2024-08-25T10:30:28Z","date_created":"2024-08-25T10:30:28Z"},{"content_type":"application/pdf","relation":"main_file","file_name":"2024-08 Farheen - JOSA B - Symmetry-protected TM modes in rib-like, plus-shaped optical waveguides with shallow etching (preprint).pdf","file_size":931810,"creator":"fossie","date_created":"2024-08-25T10:48:05Z","date_updated":"2024-08-25T10:48:05Z","access_level":"open_access","title":"(preprint)","file_id":"55753"}],"user_id":"158","keyword":["tet_topic_waveguide"],"year":"2024","type":"journal_article","doi":"10.1364/josab.528729","project":[{"name":"PhoQC: PhoQC: Photonisches Quantencomputing","_id":"266","grant_number":"PROFILNRW-2020-067"},{"_id":"167","name":"TRR 142 - B06: TRR 142 - Ultraschnelle kohärente opto-elektronische Kontrolle eines photonischen Quantensystems (B06*)","grant_number":"231447078"}],"status":"public","page":"2077","publication_status":"published","publisher":"Optica Publishing Group","has_accepted_license":"1","_id":"55751","issue":"9","date_created":"2024-08-25T10:24:58Z","author":[{"full_name":"Üstün, Necati","first_name":"Necati","last_name":"Üstün"},{"last_name":"Farheen","first_name":"Henna","orcid":"0000-0001-7730-3489","id":"53444","full_name":"Farheen, Henna"},{"full_name":"Hammer, Manfred","id":"48077","orcid":"0000-0002-6331-9348","last_name":"Hammer","first_name":"Manfred"},{"first_name":"Jens","last_name":"Förstner","orcid":"0000-0001-7059-9862","full_name":"Förstner, Jens","id":"158"}],"title":"Symmetry-protected TM modes in rib-like, plus-shaped optical waveguides with shallow etching","citation":{"apa":"Üstün, N., Farheen, H., Hammer, M., &#38; Förstner, J.
