| 摘 要： | 利用对称分步傅里叶法,数值模拟了光孤子在随机双折射光纤中的传输特性,研究了孤子间的相互作用及其非线性增益控制.结果表明,随机双折射使得孤子传输的两偏振分量脉冲强度会随着传输距离有强弱不规则的变化,但是两偏振分量的强度变化互相补充,合成孤子强度能够稳定地传输;随机双折射也增强了孤子间相互作用,非线性增益可以有效地抑制随机双折射对孤子传输相互作用的影响,使得原本会产生交叠走离的相邻孤子传输不偏离原来的时间槽,实现了对偏振模色散良好的控制作用.

| Abstract: | Symmetrical slit-step Fourier numerical method is used to simulate the soliton transmission properties in the fibers presenting randomly varying birefringence.The interactions of the optical solitons are studied,and the method of non-linear gain control is used to inhibit the interactions.The results show that the randomly varying birefringence makes the intensity of the two polarization components of the soliton change irregularly with the transmission distance,and the composite intensity of the soliton pu... |
