Abstract :
A semi-analytical method for fast simulation of microring resonators with distributed Bragg reflectors (DBR-MRR) is presented. Under the low loss condition, the structure exhibits a spectral response similar to that of a sampled-grating distributed Bragg reflector (SGDBR). However, the DBR-MRR can achieve higher reflectivity with significantly fewer gratings due to multiple reflection encounters with the same DBR gratings.
