dc.description.abstractDielectric waveguides and ring resonators are foundational structures in photonics, enabling applications such as optical frequency comb generation, filtering, and sensing. This work presents a complete formulation to analyze electromagnetic wave propagation in these structures, incorporating the shooting method to accurately calculate propagation constants, effective indices, and modal fields. With the help of the coupled-mode theory, we investigate the transmission spectrum of a Si3N4 waveguide coupled to a Si3N4 ring under the critical resonance condition. Our numerical results agree with the ones generated with COMSOL Multiphysics.
