Attributing the losses mainly to sidewall roughness, we employ a simple perturbational procedure, based on rigorously computed mode profiles of idealized channels, to estimate the attenuation for waveguides with different cross sections. A single fit parameter suffices for an adequate modelling of the effect of the waveguide geometry on the loss levels."}],"publication":"Optics Express","issue":"13","doi":"10.1364/oe.521766","language":[{"iso":"eng"}],"intvolume":"        32","date_updated":"2024-07-22T07:43:02Z","publication_status":"published","publication_identifier":{"issn":["1094-4087"]},"author":[{"full_name":"Hammer, Manfred","orcid":"0000-0002-6331-9348","last_name":"Hammer","first_name":"Manfred","id":"48077"},{"id":"63231","last_name":"Babel","first_name":"Silia","orcid":"https://orcid.org/0000-0002-1568-2580","full_name":"Babel, Silia"},{"full_name":"Farheen, Henna","last_name":"Farheen","first_name":"Henna","orcid":"0000-0001-7730-3489","id":"53444"},{"last_name":"Padberg","first_name":"Laura","full_name":"Padberg, Laura","id":"40300"},{"id":"37144","orcid":"0000-0002-5950-6618 ","first_name":"J.
