摘　　要：利用相位共轭器的频率反转特性的,补偿光纤中的色散效应,在理论上和实验上得到了证明.由色散脉冲的傅里叶交换确定了光纤中二次色散效应可以被忽略的条件,得到了共轭器的反射率和带宽与非线性介质的长度L,参数|K|L之间的关系曲线,找到了影响补偿效果的主要因素.It was proved theoretically and experimentlly that the frequency flipping of phase conjugation can be used to compensate the dispersive effect in fibers. From Fourier transformation in the dispersive optical fibers we derived the condition in which the quadratic dispersive effect in the fibers can be neglected. The curves of bandwidth and reflectivity of the conjugate mirror versus nonlinear medium length and | K| L are obtained.The Primary factors affecting compensation for fiber dispersion are found out.
