In this paper, we present numerical simulations of a refractive index sensor based on a perforated optical microring resonator. We show that the introduction of subwavelength perforations in the microring resonator increases the light-matter interaction and the sensitivity of the microring resonator. Here, the sensor performance is analyzed in two sensing schemes: bulk sensing and dielectric particle sensing. In both applications the perforated microring resonator sensor outperforms an ordinary microring resonator sensor and also maintains a high quality factor. The simulations were performed using finite-difference time domain and finite-element methods.
