Abstract
We demonstrate a high-accuracy distributed fiber optic temperature sensor using superconducting nanowire single-photon detectors and single photon counting techniques. Our demonstration uses inexpensive single-mode fiber at standard telecommunications wavelengths as the sensing fiber, which enables extremely low-loss experiments and compatibility with existing fiber networks. We show that the uncertainty of the temperature measurement decreases with longer integration periods, and that temperature uncertainty on the order of 3 K is possible with integration period as small as 60 seconds. Also, we show that the measurement exhibits unwanted polarization sensitivity, which can be reduced with a polarization diversity receiver.Citation
