矢量孤波在综合管理的双折射光纤系统中的传输

Transmission of the Vector Soliton in the Comprehensive Management System of Birefringence Fiber

以变系数的耦合非线性薛定谔方程作为光脉冲传输的理论模型,考虑了三阶色散、自频移效应、自陡峭效应和五阶非线性效应,采用对称分步傅里叶方法,数值模拟了矢量组合孤波在综合管理的双折射光纤中的传输,研究了矢量组合孤波中相邻孤子间的相互作用,并且讨论了在加入噪声干扰、功率微扰和相位微扰情况下矢量组合孤波的传输稳定性。模拟结果显示:在一定条件下,矢量组合孤波中相邻两孤子几乎不发生相互作用,能够无畸变传输;并且在有限干扰情况下,矢量组合孤波具有良好的传输稳定性和抗干扰性。

Using the coupled nonlinear Schrodinger equation with variable coefficients as the theoretical model of optical pulse transmission, and taking into account the third-order dispersion, the self-frequency shift effect, the self-steep effect and five order nonlinear effect, we numerically simulated the transmission of combined vector soliton passing through the integrated management of birefringenee fiber, and discussed the interaction of neighboring combined vector solitons, the transmission stability of the combined vector soliton when noise, power perturbation, phase perturbation were added, The results showed that the interaction of neighboring combined vector solitons were hardly happen, leading to the transmission without distortion under certain conditions. Under the condition of limited interference, the combined vector solitary waves show good transmission stability and anti-jamming.
