论文摘要
我们报告了使用双弯曲光谱法询问$π$ - 相变的纤维bragg光栅的光子温度计的精确实现。我们在1 s时达到7.5 mk的读出稳定性，并解决相似幅度的温度变化 - 对于大多数工业应用而言充足。我们的双弯道方法可以快速感知动态温度，而我们的可扩展和可重新配置的电形生成方案则可以在无激光调整的情况下具有广泛的传感范围。测试了1990年国际温度量表的可重复性，并最终受到频率参考和检查表格稳定性的限制。我们的演示为可行的多个光子设备部署到多个光子设备的通用询问器打开了大门。应用包括片测量，以同时评估温度，压力，湿度，磁场和辐射剂量等数量。
We report a precision realization of photonic thermometry using dual-comb spectroscopy to interrogate a $π$-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. Applications include on-chip measurements to simultaneously evaluate quantities like temperature, pressure, humidity, magnetic field and radiation dose.
