Abstract

In order to study the relationship between the resonant wavelength drift and the grating bending strain of a long period bending photonic crystal fiber grating sensor, based on the coupled mode theory and programming simulation, the resonant wavelength expression of long period bending photonic crystal fiber gratings was deduced. The system model of a general bending photonic crystal fiber grating sensor with long period was designed. The basic principle of the sensor was analyzed. The relationship between the bending curvature, grating refractive index, sensor resonance wavelength and grating bending strain was calculated. The results show that the grating curvature increases with the increase of the bending strain of the grating, and the resonance wavelength drift of the grating sensor increases too. The resonant wavelength drifts 0.014nm with 1 change of the grating.
