Linearity Characterization of a Dual–Parallel Silicon Mach–Zehnder Modulator

We report a high-linearity wideband dual-parallel silicon Mach-Zehnder modulator (MZM). This modulator consists of two carrier-depletion-based MZMs with a single-drive push-pull traveling wave electrode configuration. An analytic model is established to investigate the linearity property of the modulator. The measurement results show the modulator can effectively suppress third-order harmonics and...
