ABSTRACT:
A modulator includes an interferometer waveguide structure formed on an electro-optical substrate, preferably a Z-cut lithium niobate or a Z-cut lithium tantalate. The substrate includes a domain inversion between a region near the first arm and a region near the second arm of the interferometer waveguide structure. In one example, two coplanar strip electrode structures, each extending near at least a portion of the first arm and the second arm, respectively, are electrically coupled to each other.
