Abstract
Electro-optic modulators are disclosed. An electro-optic modulator includes an optical ring resonator, an optical waveguide, and a cavity of electro-optic material. The waveguide has a first portion positioned adjacent the resonator to create a first coupling region and a second portion positioned adjacent the resonator to create a second coupling region. The cavity of electro-optic material is embedded within the waveguide between the first portion and the second portion. A method of optical modulation includes the steps of receiving light into an optical waveguide, coupling a portion of the light from the waveguide into an optical ring resonator at a first coupling region between the waveguide and the resonator, transmitting the light remaining in the waveguide into a cavity of electro-optic material embedded within the waveguide, and transmitting the light from the cavity to a second coupling region between the waveguide and the resonator.
