Photonic and quantum sensors for practical integrated primary thermometry

Delivering the temperature metrology required to support advanced and emerging technologies

The kelvin redefinition has stimulated new and disruptive ways for delivering reliable and traceable temperatures: practical primary thermometry at the point of measurement. The most innovate ways to provide such traceability are photonic/quantum-based approaches.

Project takes advantage of the kelvin redefinition by developing novel small-scale photonic and quantum based primary thermometry approaches for the dissemination of thermodynamic temperatures (4–500 K).

VTT MIKES will simulate design approaches for silicon ring resonator structures and then manufacture a Si ring resonator for photonic thermometry. In addition, MIKES characterises different Si and SiN photon chips, designs and evaluates packaging techniques, calibrates photon sensors and provides full uncertainty budgets for them.
