An Effective Method to Ensure the Dark Pulse Exhibit Stable Soliton Propagation
摘要/Abstract
摘要:
通过数值模拟方法证明,采用三阶色散正负交替变化的光纤代替单一极性的常规光纤,可有效抑制三阶色散的影响,使基本暗孤子达到稳定传输.
Abstract:
Using numerical solutions of the nonlinear Schrodinger equation,we show that the effect of third-order dispersion on the stable soliton propagation of dark pulse can be significantly suppressed if third-order dispersion of the fiber is periodically alternated between the normal and anomalous regimes.
