| 摘 要： | 从耦合模方程出发,用一种矩阵方法分析了折射率调制深度误差对切趾啁啾布拉格光纤光栅传输特性的影响.结果表明:折射率调制深度误差的分布频率越高,光栅传输特性受到的危害越小;误差平均幅值越高,光栅传输特性的劣化程度越大.因此,在光栅的制作过程中,应注意避免和减小高幅值误差,并注意减少低空间频率分布的误差. |

| Abstract: | Starting from the coupled mode equations,the influence of modulation depth errors on the properties of apodized chirped fiber Bragg grating(ACFBG) is investigated theoretically by using a matrix method.The results show that the errors of low frequency distribution deteriorate the performance of ACFBG much more than the errors of high frequency distribution with the same amplitude level,and the errors of higher amplitude level lead to more performance degradation.Therefore,errors of both low frequency distri... |
