摘要
用耦合模方法和传输矩阵法相结合对长周期光栅的传输光谱特性进行了研究， 提出了用相移长周期光栅使双峰的增益谱线平坦化。理论证明， 实现这样的平坦化是可行的。
The transmission spectrum of long period grating was analized by a combination of coupled mode theory and transfer matrix method. It is suggested that a phase shifted long period grating can be used to flatten the gain spectrum with two peaks, and the result proved that such gain flattening is plausible.
