摘要
本文利用耦合模方程对正弦锥光纤光栅的反射谱进行了较为详细的计算和分析，发现，这种光纤光栅的反射谱与普通均匀周期光栅的反射谱有着很大的不同，通过控制光栅锥的形状，可得到类似于梳状滤波器的功能，对这种新型光栅在光纤激光器等方面的应用有指导意义．
Based on couple modes equations,the reflection spectrum of sine tapered fiber grating was calculated in detail.It has been found that,under different sine taper profile,the single peak of periodic grating split into two or three peaks,This kind of grating is something like a comb filter,and has good usage in WDM optical fiber communication system,multi wavelength tunable optical fiber laser etc.
