The frequency dispersion of integrated optic interferometers fabricated on different lithium niobate substrate orientations is characterized. Dispersion in the dielectric constants and the electro-optic coefficients causes most device configurations to have a significantly different electro-optic response at frequencies above and below the acoustic resonances. Only the configuration that uses the r33 electro-optic coefficient displays a broadband, well behaved frequency response.
