Abstract
For the first time, a nested-ring Mach–Zehnder interferometer (MZI) on silicon-on-insulator is realized using a complementary metal–oxide–semiconductor-based process. In this letter, we verify that the device operates in two modes: the inner-loop resonance dominant mode due to strong build-up inside the innerring, and the double-Fano resonances mode due to strong light interaction with the outer loop. The results show that the inner-loop resonance is highly sensitive to the MZI arm imbalance compared to the double-Fano resonance mode. Based on these considerations, we obtain a good fit between theory and experiment. Related Research Topics
