A study on refractive index sensors based on optical micro-ring resonators
TL;DR: In this article, the behavior of optical micro-ring resonators, especially when functioning as refractive index sensors, is studied in detail, and the optimum coupling conditions are derived and it is shown that in both cases the condition for the resonant wavelength, i.e., the wavelength at which the transmission spectrum exhibits a dip (peak), is the same and depends only on the geometrical characteristics of the circular waveguide and the effective refractive indices of the propagating mode.
