We propose a novel electro-optic modulator enhanced by nonlinear coupling dynamics. The design is similar to a conventional Mach–Zehnder modulator, but includes a nonlinear directional coupler at the output. At high enough intensities, this nonlinear coupler permits full switching for electro-optic phase shifts much less than the π required in a conventional linear device. Simulations confirm that this strategy can be used to design modulators with low drive voltage. Prospects for implementing this device are discussed.
