1. An optical device, comprising:
a waveguide including an electro-optic material having a waveguide optical refractive index and a waveguide microwave dielectric constant, the electro-optic material including lithium;
a plurality of electrodes including a first electrode and a second electrode, a portion of the waveguide being between the first electrode and the second electrode; and
a connecting dielectric, at least a portion of the connecting dielectric being between the portion of the waveguide and electrodes, the connecting dielectric having a microwave dielectric constant greater than the waveguide microwave dielectric constant.
