Chaotic laser synchronization is mainly limited by cross phase modulation in the fiber and the propagation nonlinearphaseshift is educed.
证明了光纤的交叉相位调制是限制激光混沌在光纤传输中同步的主要原因，导出了系统传输的非线性相移。

Self-phase modulation of fiber does not affect the pulse shape of chaotic signal, however, its product of nonlinearphaseshift can widen the chaotic signal spectrum.
结果表明：自相位调制不影响混沌信号脉冲的形状，但能产生非线性相移使混沌信号频谱展宽；

With theoretical analysis and numeric calculation, it is found that the transverse nonlinearphaseshift caused by the sample can be very well fitted by a Gaussian function.
