Photonic sensors offer new possibilities for the metrological temperature determination in specific applications including high electric fields or harsh environments. Within two EU projects the PTB develop and validate different kinds of photonic thermometers in a temperature range from 0 °C to over 1500 °C. The aim of this work is to develop and validate novel accurate photonic thermometers with uncertainties below 10 mK, and sensors for application within harsh environments at high temperatures. We show first results using silicon ring resonators and sapphire fiber Bragg gratings.
