摘要: The design of microring resonators (MRRs) for serial configuration, integrated in the lateral scheme was presented and simulated using 3D electromagnetic simulator based on finite integration technique. device model is embedded high index contrast (HIC) structure silicon-on-insulator with monomodal cavity TE-mode polarizations. From proposed model, we varied MRRs order, waveguides separation distance ring radius, order to evaluate influence those parameters performance terms loss, free spectral range (FSR) quality factor (Q-factor). Upon varying gap distances, it found that highest Q-factor value 1275 obtained at 150 nm radius 6 μm, while largest FSR 24 nm. trade-offs between compactness, optical bandwidth are also presented.
