For specific oblique excitation by semi-guided waves at sufficiently high angles of incidence, the idealized structures do not exhibit any radiative losses, such that reflectance and transmittance for the single port mode add strictly up to one. We consider a series of symmetric, fully and partly etched finite gratings, for parameters found in integrated silicon photonics. These can act as spectral filters with a reasonably flattop response. Apodization can lead to more box shaped reflectance and transmittance spectra. Together with a narrowband Fabry–Perot filter, these configurations are characterized by reflection bands, or transmittance peaks, with widths that span three orders of magnitude. https://ris.uni-paderborn.de/download/43245/43247/ogr-afterreview.pdf application/pdfno Optica Publishing Group2023 eng tet_topic_waveguide 0740-3224 1520-854010.1364/josab.485725 404862 Hammer, M., Farheen, H., &#38; Förstner, J.
