US Patent 7970244 Fabrication of an optical ring resonator device

An embodiment of a method for manufacturing an optical ring resonator device is disclosed. The method forms a ring resonator waveguide on a semiconductor substrate, forms an unoriented electro-optic polymer cladding over the ring resonator waveguide, and forms electrodes on the semiconductor substrate. The unoriented electro-optic polymer cladding is configured to change orientation under an applied electric field, and the electrodes are coupled to the optical ring resonator for manipulation of the electric field applied to the oriented electro-optic polymer cladding for rapid voltage tuning of its index.
