摘要: 采用数值计算方法研究了色散控制"呼吸"孤子传输系统稳定传输的特性,研究结果表明:脉冲的主体或"内核"部分的演化是稳定的,而脉冲所受的周期放大损耗以及色散项的扰动在归一化放大间距Za(Zd)1<<条件下,该扰动对脉冲主体的影响可以忽略,从而证明了色散控制"呼吸"孤子传输是一个稳定的传输方案。Abstract: The characteristic of dispersion-managed "breathing" soliton transmission is studied with numerical methods. The achieved results indicate that the main body or the core of soliton is stable and the perturbation induced from period amplifier and dispersion management can be ignored in condition of Za (Zd) 1 <<. This proves that the dispersion managed "breathing" soliton transmission is a stable transmission scheme.
