A new approach for using optical fibres as sensing elements by exploiting the evanescent field of the guided wave is proposed. The optical principle is based on the differential phase modulation between the two orthogonal polarization modes of a single-mode fibre via evanescent field interaction with sensitive thin films deposited on the side-polished fibre. A new theoretical method to calculate the matching of an anisotropic fibre-optic waveguide to a planar layer system is shown. As a practical example, a sensitive polarimetric acetone sensor is presented.
