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.","lang":"eng"}],"user_id":"158","project":[{"_id":"56","name":"TRR 142 - Project Area C"},{"_id":"75","name":"TRR 142 - Subproject C5"},{"_id":"53","name":"TRR 142"}],"type":"journal_article","title":"Hybrid coupled mode modelling of the evanescent excitation of a dielectric tube by semi-guided waves at oblique angles","author":[{"id":"48077","first_name":"Manfred","last_name":"Hammer","orcid":"0000-0002-6331-9348","full_name":"Hammer, Manfred"},{"last_name":"Ebers","full_name":"Ebers, Lena","first_name":"Lena","id":"40428"},{"first_name":"Jens","id":"158","last_name":"Förstner","orcid":"0000-0001-7059-9862","full_name":"Förstner, Jens"}],"date_created":"2020-10-24T08:03:58Z","file":[{"file_size":2212769,"creator":"fossie","date_updated":"2020-10-24T08:11:40Z","access_level":"closed","file_id":"20190","success":1,"date_created":"2020-10-24T08:11:40Z","file_name":"2020-10 Hammer - OQE - Hybrid Coupled Mode Modelling Dielectric Tube.pdf","content_type":"application/pdf","relation":"main_file"}],"doi":"10.1007/s11082-020-02595-z","ddc":["530"],"_id":"20189","status":"public","file_date_updated":"2020-10-24T08:11:40Z","publication_identifier":{"issn":["0306-8919","1572-817X"]},"citation":{"short":"M.
