摘　　要：研究了一种通过交叉相位调制(XPM)效应实现40 Gb/s信号全光3R再整形的方案,方案的核心是一个用超高非线性光子晶体光纤作为其中一臂的马赫-曾德仪,通过计算并调节这一臂的光子晶体光纤的长度,可以利用XPM效应使通过此臂的信号光产生π的非线性相移,所得光与另外一臂的光信号相干涉,实现对受噪声污染和色散影响信号净化和整形的作用。并用Optisys-tem对其进行了仿真实验。We demonstrate 3R regeneration method based on cross phase modulation in photonic crystal fiber （PCF）. The most important part of this system is a MZI optical switch which has one high-nonlinear PCF arm. By adjusting the length of the PCF, we can make the optical pulse transmitted through the PCF to obtain a phase shift about π, then interferes with the optical pulse transmitted through the other arm, the degraded data signal gets regeneration. The experiment is simulated with optisystem.
