abstract

An all fibre Mach-Zehnder interferometric configuration based on a suspended twin-core fibre is described. Due to the birefringence of the fibre cores, two interferometers were obtained by illuminating the fibre with polarized light. Applying strain, curvature and temperature to the sensing head, different sensitivities were observed, which permits the use of the matrix method to discriminate these three measurands.
