Paper Abstract

We analyze the polarization properties of uniform fiber Bragg gratings written into polarization maintaining fibers by studying the evolution with wavelength of the normalized Stokes parameters and the degree of polarization for both the reflected and transmitted signals. Theoretical expressions are derived for the Stokes parameters. Numerical simulations and experimental results are also reported. We demonstrate the possible realization of a sensor using the information contained in the evolution of teh degree of polarization in reflection. This new demodulation technique has been experimentally tested with temperature sensors.
