We fabricated an array of O-ring resonators with different graphene coverage area atop. By measuring the transmission spectra of nanophotonic devices with and without graphene, we calculated the effective absorption coefficient of the graphene on a rib silicon nitride waveguide. %K silicon nitride O-ring resonator %K ORR %R 10.1088/1742-6596/1695/1/012135 %U https://iopscience.iop.org/article/10.1088/1742-6596/1695/1/012135 %U https://doi.org/10.1088/1742-6596/1695/1/012135 %P 012135
