Abstract:
The theoretical analysis and studies are carried out to characterize the PDL spectral response of the transmitted light of the fiber Bragg grating ( FBG) subjected to local transverse force． The theoretical model for transverse force measurements utilizing PDL of the FBG is built and the transfer matrix method is also employed to simulate the polarization- dependent loss ( PDL) spectrum． The analysis indicates that the largest resonance wavelength is periodical to the applied force when the FBG is subjected to the transverse local force． Sidelobes in the PDL spectrum of FBG is the smallest and the resonance peak is the biggest when the action point of the load applied on the FBG is in the middle． The longer fiber length under force，the shorter the largest resonance wavelength．
