暗孤子耗散阻尼的周期补偿

用计算模拟方法研究了暗孤子在用光纤放大器周期补偿损耗的光纤中的传播。暗孤子对在这种系统中传播时，其亮背景会产生自激的噪声。与光纤放大器配合使用法布里－珀罗滤波器，可以消除这种噪声，有利于暗孤子的长距离稳定传播。

Periodic Compensation to Dissipative Damping of Dark solitons

Dark-soliton propagation in fibers is investigated simulatively, in the case of its dissipative damping is periodically compensated by using optical fiber amplifiers. Selfexcited noises will grow on bright backgrounds of dark-soliton pairs when they are propagating in the system. Employing of Fabry-Perot filters matched with optical fiber amplifiers can eliminate the noise and support long-distance stational propagation of dark solitons.
