Abstract: In part, the disclosure relates to opto-electrical system. The system may include a waveguide defining an optical input and an optical output; a thermo-optic phase shifter (TOPS) that includes a first electrical contact and a second electrical contact, and a resistive heater in electrical communication with the first electrical contact and the second electrical contact, the TOPS configured to change a first phase of light entering the optical input to a second phase for light exiting the optical output, the TOPS having a resistance RTOPS, the TOPS in thermal communication with the waveguide; a voltage source in electrical communication with the first electrical contact; and a resistor that includes a first end and a second end, the resistor having a resistance RS, wherein the first end is grounded, wherein the second end is in electrical communication with the second electrical contact.
