| 摘 要： | 采用传输矩阵法,分析了光纤Bragg光栅（FBG）横向局部受力时的反射谱变化.当FBG横向局部受力时,反射谱的反射峰发生分裂,且分裂点随受力的变化呈线性、周期性的移动.分裂点以11 N为周期在FBG的全波带宽内移动,周期内分裂点波长漂移相对于受力的灵敏度为0.05 nm/N.给出了仿真和实验图谱,实验结果与仿真效果一致.

| Abstract: | Fiber Bragg grating(FBG) under transverse force to a small grating section was studied by numerical simulation and experimentation.A numerical simulation based on the transfer matrix formulation approach was used to calculate the consequent changes in reflected spectrum.The reflection spectra of the FBG subjected to the transverse force split in two main peaks,and the split point shifted linearity and periodically versus the applied force.The split point was shifted in the bandwidth with the period of 11 N,and in one period the sensitivity of the split point wavelength shift versus the applied force was 0.05 nm/N.The experimental consequents show agreement with the simulation analysis. |
