| 摘 要： | 基于双折射光纤中光脉冲传输方程,详细分析了二阶色散、自相位调制以及交叉相位调制在光脉冲传输过程中引起的啁啾。分析结果显示:通过合理选取入射功率,二阶色散引起的啁啾与自相位调制引起的啁啾在脉冲中心附近可以相互抵消,从而使脉冲展宽最小;交叉相位调制产生的两偏振分量的啁啾引起的频移,可使两偏振分量间产生互束缚,利用这种现象可以抑制偏振模色散。

| Abstract: | Based on optical pulse transmission equation in birefringent optical fibers, the chirps caused by second- order chromatic dispersion, self-phase modulation, cross- phase modulation were analyzed. As a result, by choosing a right input power, the chirp caused by second-order chromatic dispersion and the chirp caused by self-phase modulation can be balanced out. The frequency shift, caused by chirp from cross-phase modulation, bring chains between two polarized parts,this can be used to restrain polarization mode dispersion. |
