title = "Investigation on fiber optic curvature sensor based on SMF-FMF-SMF structure with up-taper fusion",
abstract = "A compact fiber-optic curvature sensor based on modal interferometer (MI) in few mode fiber (FMF) is presented and investigated both in theory and experiment. The proposed MI is simply constructed by splicing a 2-centimeter-long FMF between single mode fibers (SMFs) with built-in up-taper fusion mode, i.e., SMF-FMF-SMF structure is fabricated. Both the curvature sensing performance and temperature dependency are addressed, and the result shows that curvature within a range from 0 m-1 to 1.87 m-1 can be monitored without ambiguity and the temperature sensitivity can reach up to 111 pm/°C.",
