Abstract

A simple bend sensor based on a multimode fiber combined with a twin-core fiber is proposed. The section of twin-core fiber is spliced between a section of multimode fiber and a single mode fiber. The bend shifts the interference fringe peak wavelengths which are monitored. A shift toward shorter wavelengths is observed. This device is simple to fabricate, and is used as a bend sensor with good sensitivity.
