Ring resonator based traveling wave electro optic modulator integrated with asymmetric Mach Zehnder interferometer
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.
