色散管理optical fiber中的多孤子束缚态：每时钟周期三比特光纤传输的可能性
Many-soliton bound states in dispersion-managed optical fiber: Possibility of fiber-optic transmission of three bits per clock period
摘要：
本文采用解析和数值方法研究了色散管理光纤中多孤子分子的稳定性和动力学行为，重点研究了五孤子和七孤子分子的稳定性和动力学行为。特别是，我们计算的结合力，脉冲持续时间和平衡分离使用变分方法。预测的脉冲形状与数值模拟的基础非线性薛定谔方程的结果吻合得很好。在限制范围内，具有多达七个孤子的孤子分子可能允许每个时钟周期编码三位数据。
英文摘要：
We study the stability and the dynamics of many-soliton molecules in dispersion-managed (DM) optical fibers with focus on five-and seven-soliton molecules by analytical and numerical means. In particular we calculate the binding force, pulse durations and equilibrium separations using a variational approach. Predicted pulse shapes are in good agreement with those found by numerical simulations of the underlying nonlinear Schrödinger equation. Within limitations soliton molecules with up to seven solitons possibly allow to encode three bits of data per clock period.
