Abstract

We report on the application of ultra-sensitive, nanophotonics-based sensors for temperature metrology. In particular, we present details on implementing an advanced laser locking technique to interrogate a nanobeam photonic crystal cavity temperature sensor. Our measurement technique allows a fully continuous, wide temperature rage sensor readout without breaking a laser lock over 280°C temperature range: from -40°C to 240°C, in real-time. We provide details on sensor design and fabrication, as well the measurement setup based on an advanced laser locking technique. Our photonic sensor interrogation approach can advance the photonics thermometry towards field-deployable measurement solutions.
