| 摘 要： | 提出一种新的光纤光栅综合方法,将Bragg光纤光栅的层剥离综合算法与光纤叠栅理论结合起来,层剥离综合算法根据需要的反射谱计算出光纤光栅的折射率分布,用多个带切趾函数的光纤叠栅来拟合这个折射率分布,通过改变各叠栅中的相关参数,可以得到适合需要的反射谱,相对误差一般小于4.0%。该方法具有简单、快速、易于实现的特点。

| Abstract: | A new synthetic strategy for fiber grating was proposed. For a given reflection spectrum of a fiber Bragg grating, the index profile of fiber Bragg grating could be calculated by a layer peeling algorithm. Some superimposed fiber grating with different apodisation functions were used to fit this index profile. The special reflection spectrum of a fiber Bragg grating could be realized by controlling the superimposed fiber grating's parameters adjustment.The relative error between the reflection spectrum of synthetic superimposed fiber grating and the goal spectrum is less than 4.0%. It is a sample and quick method for fiber grating synthesis problems which is easy to implement. |
