摘要:
对均匀光纤Bragg光栅(FBG)在局部横向作用力下透射信号的偏振相关损耗(PDL)特性进行了详细的理论分析和研究.建立了利用PDL实现横向应变传感的理论模型并采用传输矩阵法进行了数值模拟.分析表明,当FBG局部横向受力时,最大谐振峰随横向作用力大小呈周期变化,并且受力位置越接近FBG的中点,PDL光谱中的旁瓣越少,谐振峰的峰值越大.随着光栅受压长度的增大,最大谐振峰从长波长向短波长移动.
Abstract:
The theoretical analysis and studies are carried out to characterize the PDL spectral response of the transmitted light of the fiber Bragg grating ( FBG) subjected to local transverse force． The theoretical model for transverse force measurements utilizing PDL of the FBG is built and the transfer matrix method is also employed to simulate the polarization- dependent loss ( PDL) spectrum． The analysis indicates that the largest resonance wavelength is periodical to the applied force when the FBG is subjected to the transverse local force． Sidelobes in the PDL spectrum of FBG is the smallest and the resonance peak is the biggest when the action point of the load applied on the FBG is in the middle． The longer fiber length under force，the shorter the largest resonance wavelength．
