Abstract

In this proceeding, we present for the first time, a nested-ring Mach-Zehnder interferometer (NRMZI) on SOI (Silicon-on- insulator), realized using a CMOS based process. We show that the device operates in two propagating resonance modes: (1) The inner-loop resonant mode due to strong build-up inside the inner-ring and (2) the double Fano-resonance mode due to strong light interaction with the outer loop. The experimental data shows that the inner-loop resonance is highly sensitive to the MZI arm imbalance as compared to the double-Fano resonance mode. With such considerations, a good fit is acquired between theory and experiment.
