Abstract :

Current standards and sensors for temperature, pressure, vacuum and humidity rely mostly on century-old resistance-based metrology infrastructure, which almost reached its limits in measurement science. To drastically improve thermodynamic metrology, we propose a novel approach based on recently emerging but rapidly growing photonic technology that can provide cost-effective measurement solutions by leveraging advances in frequency metrology. In addition, this approach will align thermodynamic metrology to the emergent NIST �??Quantum SI�?� paradigm, in which a measurement has intrinsic traceability and the line between standard is blurred. In my talk, I will give two examples related to the development of �??Quantum SI�?� standards. First, I will show the results of our efforts in developing on-chip integrated silicon photonic thermometers with nanoscale footprint and ultra-high resolution that are capable to achieve measurement capabilities that are on-par or even better than the state-of-the-art resistance thermometry. In the second part of my talk, I will outline our endeavors to make Quantum-SI compatible sensors based on cold-atom technology. This effort focuses on miniaturizing, as much as physically possible, the laser cooling and trapping necessary for the creation of cold atom clouds. The resulting clouds, with temperatures < 1 mK, could be used to make a host of sensors, including clocks, inertial sensors and vacuum gauges in addition to being a possible component in emerging quantum technologies. Our present work within this program focuses on making a deployable vacuum gauge, that is primary and can measure vacuum pressures in the ultra-high vacuum to extreme high-vacuum regimes.
