Abstract
The specification describes a Mach-Zehnder electro-optic modulator device in which the ridge containing the waveguides in the interactive electro-optic regions have re-entrant sidewalls. This shifts the peak in the RF field profile to below the surface of the ridge and closer to the peak of the optical field, thereby producing a device with reduced drive voltage.
