Abstract

We report on a Bragg grating written in an eccentric-cored polymer optical fibre for measurement of strain, bend and temperature. The strain sensitivity achieves 1.13 pm με−1. The temperature response shows a negative sign with the thermal sensitivity of −50.1 pm °C−1. For bend sensing, this device exhibits a strong fibre orientational dependence, wide bend curvature range of ±22.7 m−1 and a high bend sensitivity of 63.3 pm/m−1.
