| 摘 要： | 基于离散的光纤布拉格光栅(FBG)模型,推导了时域内的传输矩阵和散射矩阵;根据因果分析,提出了一种全时域的FBG合成算法,它能直接在时域内计算已知FBG的冲激响应.这种算法在迭代求解的过程中仅使用了简单的变换和移位操作,并考虑了光在FBG中多个反射点间的来回反射,能适用于高反射率FBG的重构.FBG合成的数值模拟,证实了这种全时域算法的优越性.

| Abstract: | Based on a discrete grating model,the time-domain transfer matrix and scattering matrix are deduced.According to the causality analysis,a full time-domain algorithm for fiber Bragg grating(FBG)synthesis is proposed which can also be used to directly calculate the impulse response of a known FBG in time domain.It employs simple transforms and shift operations in the iterations and takes the feedback between multiple reflectors into account,which enable it suitable for reconstructing strong gratings.The superiority of the full time-domain algorithm is illustrated by the numerical simulations of grating synthesis. |
