The obtained data are of practical importance for tunable integrated-optical devices based on silicon nitride platform. %K grating coupler %K SiO2 %R 10.1051/epjconf/201922002009 %U https://www.epj-conferences.org/10.1051/epjconf/201922002009 %U https://doi.org/10.1051/epjconf/201922002009 %P 02009
