Abstract

A study of cladding mode loss behaviors of fiber Bragg gratings (FBG) by applying stresses is described in this paper. Under an axial compressive stress the amplitude of cladding mode losses decreased from 1.44 dB to 0.88 dB with a peak wavelength shift of 0.04 nm to shorter wavelength, while under an axial tensile stress they kept unchanged. The variation of cladding mode loss of FBG under different curvatures of bending was also studied. It was observed that the extent to which the cladding mode loss changes was related to bending directions, which indicates a non-uniform index perturbation distribution. The experimental results were explained by analyzing the mode coupling.
