We propose a 2.5-D hybrid analytical/numerical coupled mode model for the evanescent excitation of the tube through semi-guided waves propagating in the slab at oblique angles. The model combines the directional polarized modes supported by the slab with analytic solutions for the TE-, TM-, and orbital-angular-momentum (OAM) modes of the tube-shaped fiber. Implementational details of the scheme are discussed, complemented by finite-element simulations for verification purposes. Our results include configurations with resonant in-fiber excitation of OAM modes with large orbital angular momentum and strong field enhancement."}],"has_accepted_license":"1","project":[{"name":"TRR 142 - Project Area C","_id":"56"},{"_id":"75","name":"TRR 142 - Subproject C5"},{"name":"TRR 142","_id":"53"}],"file":[{"file_id":"20190","file_name":"2020-10 Hammer - OQE - Hybrid Coupled Mode Modelling Dielectric Tube.pdf","success":1,"date_created":"2020-10-24T08:11:40Z","date_updated":"2020-10-24T08:11:40Z","creator":"fossie","file_size":2212769,"content_type":"application/pdf","access_level":"closed","relation":"main_file"}],"doi":"10.1007/s11082-020-02595-z","article_number":"472","publication_status":"published","ddc":["530"],"user_id":"158","citation":{"bibtex":"@article{Hammer_Ebers_Förstner_2020, title={Hybrid coupled mode modelling of the evanescent excitation of a dielectric tube by semi-guided waves at oblique angles}, volume={52}, DOI={<a href=\"https://doi.org/10.1007/s11082-020-02595-z\">10.1007/s11082-020-02595-z</a>}, number={472}, journal={Optical and Quantum Electronics}, author={Hammer, Manfred and Ebers, Lena and Förstner, Jens}, year={2020} }","mla":"Hammer, Manfred, et al. “Hybrid Coupled Mode Modelling of the Evanescent Excitation of a Dielectric Tube by Semi-Guided Waves at Oblique Angles.” <i>Optical and Quantum Electronics</i>, vol. 52, 472, 2020, doi:<a href=\"https://doi.org/10.1007/s11082-020-02595-z\">10.1007/s11082-020-02595-z</a>.","ama":"Hammer M, Ebers L, Förstner J.
