弯曲长周期光子晶体光纤光栅传感器的研究
Research of long period bending photonic crystal fiber grating sensors
摘要
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 1με change of the grating .关键词
