Ultra-Sensitive Strain and Temperature Sensing Based on Single-Mode-Multimode-Single-Mode Structure Comprising Perfluorinated Plastic Optical Fibers

摘要：

　　We implement the strain and temperature sensors based on multimode interference in perfluorinated graded-index (GI) plastic optical fibers,and investigate their sensing performance at 1300 nm.At room temperature,we achieve ultra-high sensitivities of strain and temperature of-112pm/με/m and +49.8 nm/℃/m,the absolute value of which are approximately 12.9 and over 1800 times as large as those in silica GI multimode fibers,respectively.We also find that the temperature sensitivity is drastically enhanced with increasing temperature toward~80℃,where glass transition of core polymer partially occurs.
