  • Method and device for substantially eliminating optical damage in lithium niobate devices
    Patent number: 11366268
    Abstract: An integrated optical device includes a substrate. A waveguide includes a lithium niobate. A TiO2 coating 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.
    Type: Grant
