Abstract
An optical waveguide is formed in an integrated optics chip that includes a substrate formed of an electrooptically active material. The optical waveguide network has an input facet where optical signals may be input to the optical waveguide network and an output facet where optical signals may be output from the optical waveguide network. A structure is located in an upper layer of the substrate to prevent surface waves that propagate in the substrate from cross coupling into the output facet.
