Abstract
A method of forming an electro-optical modulator including forming a lithium-niobate (LN) wafer including an optical waveguide situated within and proximate a first side of the LN wafer; bonding the LN wafer to a substrate such that the first side of the LN wafer faces the substrate; thinning the LN wafer; and forming coplanar transmission lines over and/or on a second side of the LN wafer, wherein the coplanar transmission lines extend parallel with and are laterally on either side of the optical waveguide.
