Dual electro-optic frequency comb photonic thermometry
Data from peer-reviewed publication: A. J. Fleisher et al., Dual electro-optic frequency comb photonic thermometry, Optics Letters. We report a precision realization of photonic thermometry using dual-comb spectroscopy to interrogate a ?-phase-shifted fiber Bragg grating. We achieve read-out stability of 7.5 mK at 1 s and resolve temperature changes of similar magnitude?sufficient for most industrial applications. Our dual-comb approach enables rapid sensing of dynamic temperature, and our scalable and reconfigurable electro-optic generation scheme enables a broad sensing range without laser tuning. Reproducibility on the International Temperature Scale of 1990 is tested, and ultimately limited by the frequency reference and check-thermometer stability. Our demonstration opens the door for a universal interrogator deployable to multiple photonic devices in parallel to potentially unravel complex multi-physical quantity measurements.
