Abstract
A method for operating an optical system may include selecting a band gap energy level for an optical waveguide in an electro-optic modulator. The band gap energy level may correspond to a predetermined phase shift efficiency of a waveguide electrode coupled to the optical waveguide. The method may further include generating, across a conductive plane in the electro-optic modulator, a differential voltage that produces a predetermined temperature in a waveguide core of the optical waveguide. The predetermined temperature may correspond to the band gap energy level selected for the optical waveguide. The method may further include transmitting, through the optical waveguide and with a modulating voltage applied by the waveguide electrode, an optical wave to an optical wave combiner. The modulating voltage may produce an amount of phase shift in the optical wave at the predetermined phase shift efficiency.
