我们在全氟（PF）渐变折射率（GI）塑料光纤中实现了基于多模干涉的应变和温度传感器，并研究了它们在1300 nm处的传感性能。我们得到了-112 pm/με/m和+49.8 nm/°C/m的应变和温度灵敏度，其绝对值分别是石英GI多模光纤的12.9倍和1800倍以上。这些超高应变和温度敏感性可能源于独特的芯材料，即，PF聚合物。
We implement the strain and temperature sensors based on multimode interference in perfluorinated (PF) graded-index (GI) plastic optical fibers, and investigate their sensing performance at 1300 nm. We obtain strain and temperature sensitivities of -112 pm/με/m and +49.8 nm/°C/m, the absolute value of which are 12.9 and over 1800 times as large as those in silica GI multimode fibers, respectively. These ultra-high strain and temperature sensitivities probably originate from the unique core material, i.e., PF polymer.
