We consider a multimode step-index fiber with a high-index coating, where the waves in the slab are evanescently coupled to the modes of the fiber. Conditions for effective resonant interaction are identified. Based on a hybrid analytical–numerical coupled mode model, our simulations predict that substantial fractions of the input power can be focused into waves with specific orbital angular momentum, of excellent purity, with a clear distinction between degenerate modes with opposite vorticity.","lang":"eng"}],"file_date_updated":"2021-04-30T11:59:16Z","author":[{"id":"48077","first_name":"Manfred","full_name":"Hammer, Manfred","last_name":"Hammer","orcid":"0000-0002-6331-9348"},{"id":"40428","first_name":"Lena","full_name":"Ebers, Lena","last_name":"Ebers"},{"first_name":"Jens","id":"158","orcid":"0000-0001-7059-9862","last_name":"Förstner","full_name":"Förstner, Jens"}],"year":"2021","user_id":"158","language":[{"iso":"eng"}],"_id":"21932","title":"Resonant evanescent excitation of guided waves with high-order optical angular momentum","type":"journal_article","volume":38,"keyword":["tet_topic_waveguides"],"date_updated":"2022-01-06T06:55:20Z","page":"1717","intvolume":"        38","oa":"1","department":[{"_id":"61"},{"_id":"230"}],"publication_identifier":{"issn":["0740-3224","1520-8540"]},"publication_status":"published","issue":"5","project":[{"name":"TRR 142 - Project Area C","_id":"56"},{"_id":"53","name":"TRR 142"},{"name":"TRR 142 - Subproject C5","_id":"75"}],"citation":{"mla":"Hammer, Manfred, et al. “Resonant Evanescent Excitation of Guided Waves with High-Order Optical Angular Momentum.” <i>Journal of the Optical Society of America B</i>, vol. 38, no. 5, 2021, p. 1717, doi:<a href=\"https://doi.org/10.1364/josab.422731\">10.1364/josab.422731</a>.","bibtex":"@article{Hammer_Ebers_Förstner_2021, title={Resonant evanescent excitation of guided waves with high-order optical angular momentum}, volume={38}, DOI={<a href=\"https://doi.org/10.1364/josab.422731\">10.1364/josab.422731</a>}, number={5}, journal={Journal of the Optical Society of America B}, author={Hammer, Manfred and Ebers, Lena and Förstner, Jens}, year={2021}, pages={1717} }","ieee":"M.
