Abstract

We proposed and theoretically investigated a ring resonator-based traveling-wave electro-optic modulator integrated with asymmetric Mach–Zehnder interferometer (AMZI). The AMZI improved the modulation sensitivity and response of the modulator. A 2.93-fold increase in modulation sensitivity was achieved when compared with conventional Mach–Zehnder (MZ) modulators. A traveling-wave analysis of this modulator was presented for the first time. The simulation results showed that the modulator had superior performance compared to conventional ring modulators and MZ modulators. A modulation up to 275 GHz was achieved in the presence of both microwave loss and velocity mismatch.
