Abstract

The curvature- or bend-sensing response of long-period gratings (LPG) UV-inscribed in D-shaped fibre has been investigated experimentally. Strong fibre orientation dependence of the spectral response when such LPGs are subjected to dynamic bending has been observed and is shown to form the basis for new vector sensors.
