It is pointed that the apodization of the fiber grating by using Moiré effect is a pure apodization because the Moiré effect makes the index modulation amplitude in both positive and negative sides and keeps the average index unchanged.
从理论上分析了利用莫尔效应进行变迹所引起的光纤光栅反射谱和色散特性的变化 ,指出由于莫尔条纹状的折射率调制使平均有效折射率在光栅区维持不变 ,所以可以实现纯变迹。
