Abstract

In this article, we consider the coupled Ginzburg–Landau equation with variable coefficients including the nonlinear gain and obtain the exact solutions of chirped dark vector quasi-solitons via the ansatz method. Next, the propagation of chirped dark vector quasi-solitons is discussed to verify whether they can be transmitted stably in the birefringent optical fiber system. The numerical simulation shows that this can be achieved. We deeply add the small perturbation to the transmission of dark vector quasi-solitons to make the results above more general. The results further prove the correctness of our solutions.

非线性增益双折射光纤系统中啁啾暗矢量准孤子的传输稳定性
本文考虑了含非线性增益的变系数耦合金兹堡-朗道方程,利用ansatz方法得到了啁啾暗向量拟孤子的精确解。其次,讨论了啁啾暗矢量准孤子的传播,验证了它们在双折射光纤系统中是否可以稳定传输。数值模拟表明,这是可以实现的。我们在暗向量准孤子的传输中深入地加入了小摄动,使上述结果更具一般性。结果进一步证明了我们的解决方案的正确性。
