Abstract

We present a compact in-line fiber interferometric sensor fabricated in a boron doped two-mode highly birefringent microstructured fiber using a CO 2 laser. The intermodal interference arises at the fiber output due to coupling between the fundamental and the first order modes occurring at two fiber tapers distant by a few millimeters. The visibility of intermodal interference fringes is modulated by a polarimetric differential signal and varies in response to measurand changes. The proposed interferometer was tested for measurements of the strain and temperature, respectively, in the range of 20 700 ° C and 0 17 mstrain . The sensitivity coefficients corresponding to fringe displacement and contrast variations are equal respectively for strain 2.51 nm / mstrain and 0.0256 1 / mstrain and for temperature 16.7 pm / ° C and 5.74 × 10 5 1 / ° C . This allows for simultaneous measurements of the two parameters by interrogation of the visibility and the displacement of interference fringes.
