In this work perforated microring resonator based refractive index sensor is presented. Numerical analysis of the microring using COMSOL Multiphysics® was performed. From transmission spectra sensitivity and quality factor of our proposed structure were evaluated. It was shown that perforated microring resonator exhibits higher sensitivity than ordinary microring resonator while also maintaining high quality factor.
