Abstract
An integrated optical device includes a substrate. A waveguide includes a lithium niobate. A TiOcoating is disposed at least in part over a longitudinal surface of the waveguide as a coated waveguide supported by the substrate. A silicon oxide substantially can cover and surround the waveguide in cross section over a longitudinal direction of said waveguide as an optical cladding. A method for substantially eliminating optical damage in lithium niobate devices is also described.
