Patent ID: 6931192

Claim:
A process wherein an electrooptic waveguide is formed by: providing a waveguide substrate; positioning an optical waveguide core over a first surface of said substrate; providing a waveguide superstrate; forming at least two control electrodes on a first surface of said superstrate, wherein said control electrodes define selected electrode thicknesses; positioning a viscous electrooptic cladding material over one or both of said first surface of said substrate and said first surface of said superstrate; and urging said first surface of said waveguide substrate and said first surface of said waveguide superstrate toward each other to create a layer of cladding material between said surfaces, wherein said cladding material defines a cladding material viscosity selected to permit dispersion of said cladding material about said control electrodes and said core as said first surface of said waveguide substrate and said first surface of said waveguide superstrate are urged toward each other, and said cladding material is provided in a quantity sufficient to ensure that said layer of cladding material defines a cladding layer thickness at least as large as said selected electrode thicknesses.
