Multicore Fiber Bending Sensors with High Sensitivity Based on Asymmetric Excitation Scheme

Multicore Fiber Bending Sensors with High Sensitivity Based on Asymmetric Excitation Scheme

Bending sensing was realized by constructing a tapered four-core optical fiber (TFCF) sensor. The four-core fiber (FCF) between the fan-in and fan-out couplers was tapered and the diameter became smaller, so that the distance between the four cores arranged in a square became gradually smaller to pr...
