Abstract

Based on the attractive elasto-optic properties of single-mode microstructured polymer optical fibres (SM mPOFs) reported elsewhere,10 mode polarisation may be used as sensing probe for several parameters of interest like mechanical pressure. We report on a simplified detection scheme that does not require measuring the actual polarisation state of the light emerging from the mPOF. A polariser and a photodetector in a proper configuration are only required. The detected light intensity shows a high linearity with applied force to the mPOF.
