Abstract:
An optical waveguide device comprising:an electro-optical crystal substrate having a top surface and a bottom surface; an optical waveguide path formed within a surface of the electro-optical crystal substrate; at least one electrode positioned above the optical waveguide path for applying an electric field to the optical waveguide path; a silicon titanium oxynitride layer; a connector for interconnecting the silicon titanium oxynitride layer to another surface of the electro-optical crystal substrate that is opposite to the surface in which the optical waveguide path is formed; and an additional silicon titanium oxynitride layer for temporal stabilization doped with a metal from columns 3-16 of the Periodic Table, in metal or oxide form, is positioned between the silicon titanium oxynitride layer and the electro-optical crystal substrate.
