Komrakova S, Kovalyuk V, An P, Golikov A, Rybin M, Obraztsova E, et al. Effective absorption coefficient of a graphene atop of silicon nitride nanophotonic circuit. In: J. Phys.: Conf. Ser. Vol 1695.; 2020. 012135.
Abstract: In this paper, we demonstrate the results of a study of the optical absorption properties of graphene integrated with silicon nitride O-ring resonator. 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.

Elmanova A, An P, Kovalyuk V, Golikov A, Elmanov I, Goltsman G. Study of silicon nitride O-ring resonator for gas-sensing applications. In: J. Phys.: Conf. Ser. Vol 1695.; 2020. 012124.
Abstract: In this work, we experimentally studied the influence of different gaseous surroundings on silicon nitride O-ring resonator transmission. We compared the obtained results with numerical calculations and theoretical analysis and found a good agreement between them. Our results have a great potential for gas sensing applications, where a compact footprint and high efficiency are desired simultaneously.
