Temperature is one of the most measured quantity in the world, second only to time. Recently there has been considerable interest in developing photonic temperature sensors to leverage advancements in frequency metrology. Here we show that Silicon based ring resonator devices can resolve temperature differnces of 1 mK. An even lower noise floor of 80 μK is achieved in the side of fringe constant power mode measurement.
