    Abstract: A method for fabricating titanium-indiffusion waveguides in optical modulators and other optical waveguide devices includes disposing titanium strips in a waveguide pattern on the surface of a crystalline substrate, such as lithium niobate or lithium tantalate, and indiffusing the titanium atoms into the crystalline substrate by pressurizing above ambient atmospheric pressure an oxygen gas atmosphere enclosing the crystalline substrate, heating in the oxygen gas atmosphere, maintaining temperature and pressure for an indiffusion period, and cooling to ambient temperature. A powder formed of the same chemical composition as the crystalline substrate may be introduced into the indiffusion process to limit the crystalline substrate from outgassing alkaline earth metal oxide during the indiffusion period. An indiffusion container that allows for crystalline substrates to be annealed in the presence of a powder without contaminating the substrate with the powder during the indiffusion process may be used. Waveguides manufactured in accordance with the method exhibit superior drift performance.

    Abstract: The present invention relates to a Mach-Zehnder optical modulator having an electrode structure that is arranged to compensate for temperature induced performance degrading variations. The distances between appropriate faces of the signal electrode and a ground electrode and corresponding wave-guide arms are arranged such that there is a more balanced thermal expansion of the waveguide arms due to heating of the waveguides by the RF signals carried on the signal and ground electrodes. Tailored buffer layers further balances the heating in the waveguide arms through the RF losses in the electrodes. The balanced heating reduces the temperature gradient between the waveguide arms of the optical modulator and hence reduces the adverse thermally induced performance degrading variations.
