预啁啾技术中瞬态啁啾特性的分析

Analysis of Transient Chirp in Prechirp Technique

预啁啾技术作为光纤色散的一种补偿技术已经提出［１，２］，本文针对此技术中瞬态啁啾的作用进行了详尽的分析，得出它将会导致传输能量损失的结论，最后本文提出了通过采用最佳延时来消除该影响的方法，并计算出了不同参数下的最佳延迟时间．

Prechirp technique has been proposed as a method to compensate dispersion of optical fiber. This paper analyzes the transient chirp in this technique in detail and gets a conclusion that it will cause energy penalty. At last we recommend a method using optimal delay to get rid of this influence,and this delay is calculated with different parameters.
