When a highly-birefringent fibre is stretched, the birefringence changes. The phenomenon is shown to result from a difference in Poisson's ratio of the two glasses from which the fibre is constructed. Experimental verification is given and a simple polarimetric strain gauge made from bow-tie fibre is demonstrated.
