Abstract

An optical device may include a planar lightwave circuit (PLC) waveguide to guide an optical signal. The optical device may include a thermo-optic phase shifter to receive a control signal for controlling a temperature of the thermo-optic phase shifter, the temperature of the thermo-optic phase shifter being used to apply a phase shift to the optical signal in the PLC waveguide, and adjust the temperature of the thermo-optic phase shifter based on the control signal. The optical device may include a feedback component to generate feedback associated with applying the phase shift. The optical device may include a controller to adjust the control signal based on the feedback, the control signal being adjusted to reduce a response time of the thermo-optic phase shifter in applying the phase shift.
