ABSTRACT:
A method is provided for stabilizing an electro-optic substrate employed in a waveguide device. The method comprises cleaning a surface of the substrate, and exposing the device to a reactive oxide to passivate the surface. A layer of sealant is deposited on the substrate in a vacuum to seal the surface.
