Abstract

A method for measuring sensitivity of Bragg gratings to external parameters for different spatial and polarization modes is presented, along with the results of sensitivity measurements to temperature and elongation for LP₀₁^x, LP₀₁^y, LP₁₁^x, LP₁₁^y modes. The difference in responses according to the type of mode shows the possibility of simultaneous temperature and elongation measurement using two-mode Bragg gratings.
