摘要
基于耦合模理论和传输矩阵法,引入分段切趾(变迹)技术,对线性啁啾光纤BRAGG光栅进行分析。以5段对称切趾为例,对切趾后光纤的反射谱、时延曲线等特性进行数值分析,对比传统的单一函数完全切趾和对称切趾技术,说明分段切趾对光纤光栅性能的优化作用。
Analysis of linear chirped Bragg optical fiber grating by piecewise apodised technology bases on the couple-mode theory and the transfer matrix approach. This paper analyses the characters of reflection spectrum and time delay curves with an example of 5 symmetrically apodised grating segments. Comparing the result with traditional technology： whole apodised and symmetrically apodised technology, the study proves the advantages of piecewise apodised method.
