A Mach–Zehnder interferometer (MZI) composed of electro-optical polymer/silicon hybrid slot waveguides is reported. The device is designed to be asymmetrical so that the modulator is in a linear workspace when no electric field is applied to the initial operating state. We rely on the fast and stron...
