【摘要】：飞秒孤子作为未来大容量、大数据光纤通信的载流已经成为了当前重要研究方向,建立了标准单模光纤存在噪声时的波解体和孤子形成模型。分析结果表明:对于长于200 ps的脉冲,即使是低噪声功率,波解体调制不稳定性机制会导致噪声放大;当脉冲短于20 ps,波解体实现大量孤子是由于脉冲崩溃和脉冲谱展宽,而在它们之间的脉冲时波解体实现大量孤子主要是由于脉冲崩溃。脉冲调制的结果对于克服光纤损耗及非线性有一定的理论和实际意义。
[Abstract]:Femtosecond solitons as a large capacity in the future, the carrier current of big data optical fiber communication has become an important research direction at present. The wave disintegration and soliton formation model of standard single-mode fiber with noise are established. The results show that for pulses longer than 200 PS, even at low noise power, the mechanism of wave disintegration modulation instability will lead to noise amplification, and when the pulse is shorter than 20 ps, a large number of solitons are realized because of pulse collapse and pulse spectrum broadening. However, the breakup of the pulse wave between them is mainly due to the pulse collapse in order to realize a large number of solitons. The results of pulse modulation have theoretical and practical significance for overcoming fiber loss and nonlinearity.
