In this paper, the spectral characterization of polarization dependent loss (PDL) of locally pressed fiber Bragg grating (FBG) is analyzed. The evolution of the PDL response of a FBG as functions of the load magnitude the loaded length of the grating and the position of the load are studied. The physical model is presented and a numerical simulation based on the modified transfer matrix method is also used to calculate the PDL response of the FBG. The theoretical analysis and numerical simulation suggest that the PDL response of the FBG has potential applications for distributed diametric load sensor. Good agreements between experimental results and numerical simulations have been obtained.
