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"}],"_id":"3894","publisher":"The Optical Society","urn":"38942","page":"3711-3714","volume":40,"ddc":["530"],"user_id":"158","status":"public","has_accepted_license":"1","oa":"1","citation":{"ama":"Hammer M, Hildebrandt A, Förstner J.
