Abstract
Electro-optic (EO) modulators are disclosed. The EO modulators include a substrate and an EO material layer disposed over the substrate. The EO material layer and the substrate provide an optical waveguide having an optical group velocity (OGV). The EO modulators also include electrodes disposed over the EO material layer to provide a coplanar waveguide (CPW). The CPW has a radio-frequency (RF) phase velocity, and the electrodes have a gap therebetween. The EO modulators also include a superstrate disposed over the EO material layer and configured to be raised and lowered, or disposed and removed to tune the RF phase velocity to be substantially the same as the OGV, wherein a space exists between the superstrate and the EO material.
