摘要
研究了线性啁啾长周期光纤光栅的交叉耦合常数以及高阶二次方啁啾对光纤光栅滤波器的影响 .研究发现 ,因交叉耦合常数的不同 ,滤波器可以是带通、带阻、或是部分带通带阻的 .高阶二次方啁啾对长周期光纤光栅滤波器的影响不仅表现在滤波器透射率的变化 。
This paper investigated the transmission of the long-period fiber grating in the linear chirp and in the nonlinear quadric chirp, and detailed the grating's parameters L, Kac and chirp f,which affect the transmission of fiber grating. With various cross-coupled constants, the filter can be band-pass, band-reject or partial band pass/reject. The effects of the high order quadric chirp on the long-period fiber grating were in transmission and in the shift of the resonant wavelength.
