摘要：

We report a precision realization of photonic thermometry using dual-comb spectroscopy to interrogate a it-phase -shifted fiber Bragg grating. We achieve readout stability of 7.5 mK at 1 s and resolve temperature changes of simi-lar 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 lim-ited by the frequency reference and check-thermometer stability. Our demonstration opens the door for a univer-sal interrogator deployable to multiple photonic devices in parallel to potentially unravel complex multi-physical quan-tity measurements.
