Microring resonators are used in nonlinear optics, single-photon generation, and on-chip optical filters because of their high quality and easy manufacturing process. In this study, a silicon-nitride split microring resonator on a silicon dioxide ring is proposed, and the resonator characteristics were analyzed using the three-dimensional finite-difference time-domain method. A gap was introduced into a 4 ㎛ radius ring resonator to operate in the 760 ㎚ -wavelength region, and a SiO₂ post structure was installed under the ring resonator to obtain a high quality factor (Q-factor). A Q-factor of 2000 was obtained even in a microring resonator structure with a 50 ㎚ gap, and the light was strongly confined in the gap. The split-ring-resonator structure proposed in this study is expected to be applied to optical refractive index sensors.
