The spectrometer exploits the modal dispersion in planar waveguides in a layout with slab regions having two different thicknesses of the guiding layer. The set-up uses parabolic mirrors, for the collimation of light of the input waveguide and focusing of the light to the receiver waveguides, which relies on total internal reflection at the interface between two such regions. These regions are connected adiabatically to prevent unwanted mode conversion and loss at the edges of the prism. The structure can be fabricated with two wet etching steps. The paper presents basic theory and a general approach for device optimization. The latter is illustrated with a numerical example assuming SiON technology.","lang":"eng"}],"language":[{"iso":"eng"}],"doi":"10.1016/j.optcom.2015.11.066","publication_identifier":{"issn":["0030-4018"]},"author":[{"full_name":"Civitci, F.","last_name":"Civitci","first_name":"F."},{"id":"48077","last_name":"Hammer","first_name":"Manfred","orcid":"0000-0002-6331-9348","full_name":"Hammer, Manfred"},{"full_name":"Hoekstra, H.J.W.M.","last_name":"Hoekstra","first_name":"H.J.W.M."}],"title":"Planar prism spectrometer based on adiabatically connected waveguiding slabs","year":"2015","article_type":"original","intvolume":"       365","publication_status":"published","date_updated":"2022-01-06T06:59:44Z","citation":{"apa":"Civitci, F., Hammer, M., &#38; Hoekstra, H.
