双折射下啁啾光栅径向局部受压特性研究
|
摘要
采用光学分析和实验相结合的方法,分析了啁啾光纤布拉格光栅(CFBG)径向局部受压时的双折射现象、啁啾光栅径向局部受压时的光谱变化以及双折射对径向局部受压啁啾光栅光谱的影响。对所观察到光谱响应的突出特点进行了定性解释,以获得对光栅局部受压特性的真实洞悉。结果表明:受压处反射谱的下沉幅度随着受压载荷的增加而增大。实验结果与理论分析一致。
Combining optical analysis with experimertal method,birefringence of chirped fiber Bragg grating(CFBG) under diametric force to grating section,reflection spectra of the CFBG and effects on birefringence to the CFBG under local diametric pressure are studied.The prominent features observed in the spectral responses are qualitatively explained in order to gain physical insight into the nature of locally pressed gratings.The results show that the dipping in reflection spectra of the CFBG under local diametric pressure is greater when the pressured load is larger.The experimental results show very good correspondance with the theoretical analysis.
