Paper Abstract

This work presents a temperature independent strain/load sensor using a highly birefringent photonic crystal fibre loop mirror. The length of the sensing head is 38 centimetres and its corresponding wavelength spacing between two interferometer minima is 8 nm. The obtained strain and transverse load sensitivity were 1.21 pm/&mgr;&Vegr; and 0.37 nm/Kg/mm, respectively, while is insensitive to temperature (0.3 pm/°C).
