Photonic and Optomechanical Sensors for Nanoscaled and Quantum Thermometry: The EU Project PhotOQuanT

Photonic sensors use light-matter interaction to measure temperature via temperature-dependent material properties. A particularly promising new development is the possibility of using optomechanical sensors to produce quantum primary standards. Photonic and optomechanical temperature sensors enable a spatial resolution adapted to applications where usual temperature sensors are unsuitable. This project will develop photonic and optomechanical sensors for the measurement of temperature at micrometer length scale. These sensors will be of prime importance for the future dissemination of the kelvin following its forthcoming re-definition in 2018.
