High Sensitivity Strain Sensors Using Four-Core Fibers through a Corner-Core Excitation

High Sensitivity Strain Sensors Using Four-Core Fibers through a Corner-Core Excitation

A weakly-coupled multicore fiber can generate supermodes when the multi-cores are closer to enter the evanescent power coupling region. The high sensitivity strain sensors using tapered four-core fibers (FCFs) were demonstrated. The fan-in and fan-out couplers were used to carry out light coupling b...
