Transfer of\r\noptical power carried by planar, semi-guided waves is possible without reflections or radiation losses, and over large\r\nvertical distances. This functionality is realized through simple step-like folds of high-contrast dielectric slab waveguides, in combination with oblique wave incidence, and fulfilling a resonance condition. Radiation losses vanish, and polarization conversion is suppressed for TE wave incidence beyond certain critical angles. This can be understood by fundamental arguments resting on a version of Snell’s law. The two 90° corners of a step act as identical partial reflectors in a Fabry–Perot-like resonator setup. By selecting the step height, i.e., the distance between the reflectors, one realizes resonant states with full transmission. Rigorous quasi-analytical simulations\r\nfor typical silicon/silica parameters demonstrate the functioning. Combinations of several step junctions can lead\r\nto other types of optical on-chip connects, e.g., U-turn- or bridge-like configurations.","lang":"eng"}],"file":[{"content_type":"application/pdf","file_name":"2015-07 Hammer,Hildebrandt,Förstner_How planar optical waves can be made to climb dielectric steps_Optics Letter.pdf","relation":"main_file","date_updated":"2018-09-04T19:35:48Z","access_level":"open_access","file_id":"3895","file_size":1504149,"creator":"hclaudia","date_created":"2018-08-13T09:41:32Z"}],"has_accepted_license":"1","date_updated":"2022-01-06T06:59:51Z","language":[{"iso":"eng"}],"date_created":"2018-08-13T09:39:06Z","user_id":"158","keyword":["tet_topic_waveguide"],"author":[{"first_name":"Manfred","last_name":"Hammer","full_name":"Hammer, Manfred","orcid":"0000-0002-6331-9348","id":"48077"},{"last_name":"Hildebrandt","full_name":"Hildebrandt, Andre","first_name":"Andre"},{"first_name":"Jens","last_name":"Förstner","id":"158","orcid":"0000-0001-7059-9862","full_name":"Förstner, Jens"}],"volume":40,"citation":{"apa":"Hammer, M., Hildebrandt, A., &#38; Förstner, J.
