虽然人们已经在实验上研究了由非晶二氧化硅(a-SiO2)制成的光纤的折射率(RI)的温度依赖性,但是在以前的实验中,温度范围通常低于800 K,并且仍然缺乏用于实验结果的严格的理论模型。本文从理论和实验两方面研究了a-SiO_2折射率的温度依赖性,首次利用光纤延迟线在301-1275 K温度范围内进行了实验研究,理论结果与实验结果符合较好。我们的工作在光纤延迟线温度传感器中具有潜在的应用价值。
Though people have experimentally studied the temperature dependence of the refractive index (RI) of optical fibers made of amorphous silica (a-SiO2), the temperature ranges in the previous experiments are usually below 800 K, and a rigorous theoretical model for the experimental results has still been absent. In this paper, the temperature dependence of the RI of a-SiO2is studied theoretically and experimentally, where by means of an optical fiber delay line, the experiment is carried out in the temperature range of 301–1275 K for the first time, and the theoretical result agrees well with the experimental one. Our work has potential application in temperature sensors by means of optical fiber delay lines.
