1. An apparatus for an optical device based on differential thermal control, the apparatus comprising:

  • a dielectric base;

    a pair of waveguides on the dielectric base, the waveguides having substantially similar lengths and extending in parallel for their lengths;

    on the dielectric base, a single continuous layer of a thermo-electric material in contact with the pair of waveguides, wherein the continuous layer of the thermo-electric material is extended at least between outer sides of the waveguides across both waveguides, and along the length of the waveguides; and

    on the thermo-electric material, a pair of electrodes extended next to the waveguides and along the length of the waveguides.
