我们提出了一种用于高温测量（高达1000摄氏度）的小型光纤法布里-珀罗探头。它是由一小段保偏光子晶体光纤（PMPCF）和一根单模光纤（SMF）熔接而成。单模光纤的纤芯与PMPCF的空气孔之间的界面以及PMPCF的端面作为反射镜。PMPCF的纯石英芯被用作敏感元件。实验结果表明，该探针具有较高的热稳定性，温度灵敏度可达15.34pm/℃，且不受PMPCF长度的影响。温度响应的线性度高达99.83%。该传感器具有制作工艺简单、成本低、体积小、重复性好等优点，具有良好的实际应用前景。(C)2020美国光学学会
We propose a miniaturized optical fiber Fabry-Perot probe for high temperature measurement (up to 1000 degrees C). It is simply fabricated by fusion splicing a short section of polarization-maintaining photonic crystal fiber (PMPCF) with a single-mode fiber (SMF). The interface between the core of the SMF and air holes of the PMPCF, and the end face of the PMPCF work as the mirrors. The pure silica core of the PMPCF is employed as the sensing element. Experimental results show that the probe has a high thermal stability and the temperature sensitivity reaches up to 15.34 pm/degrees C, which is not affected by the length of the PMPCF. The linearity of temperature response is as high as 99.83%. The proposed sensor has promising prospects in practical applications due to simple fabrication process, low cost, compact size, and excellent repeatability. (C) 2020 Optical Society of America
