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。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.
