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 cladding having a cladding optical dielectric constant and a cladding microwave dielectric constant, the cladding being on the waveguide; and
a connecting dielectric, at least a first portion of the connecting dielectric having a microwave dielectric constant greater than the cladding microwave dielectric constant, at least a second portion of the connecting dielectric being between the waveguide and the plurality of electrodes.
