【摘要】：飛秒孤子作為未來大容量、大數(shù)據(jù)光纖通信的載流已經(jīng)成為了當(dāng)前重要研究方向,建立了標(biāo)準(zhǔn)單模光纖存在噪聲時的波解體和孤子形成模型。分析結(jié)果表明:對于長于200 ps的脈沖,即使是低噪聲功率,波解體調(diào)制不穩(wěn)定性機制會導(dǎo)致噪聲放大;當(dāng)脈沖短于20 ps,波解體實現(xiàn)大量孤子是由于脈沖崩潰和脈沖譜展寬,而在它們之間的脈沖時波解體實現(xiàn)大量孤子主要是由于脈沖崩潰。脈沖調(diào)制的結(jié)果對于克服光纖損耗及非線性有一定的理論和實際意義。
[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.
