PTAT Temperature Sensor for Micro-Ring Resonator Thermal Stabilization
Team member: Saman Saeedi

As the resonance wavelength of micro-ring modulators is susceptible to temperature fluctuations, they require thermal tuning. Sophisticated techniques and circuitry have been proposed to stabilize the temperature fluctuations in micro-ring modulators such as output optical power feedback, bit error-rate (BER) feedback, feedback through scattered light. These techniques require extra optical power on the silicon-photonic chips or complex circuitry for implementation. In this project a monolithic PTAT temperature sensor is proposed for thermal stabilization of micro-ring resonator modulators through direct measurement of temperature.
