1、摘要孤子現(xiàn)象存在于眾多領(lǐng)域中，自孤子波在十九世紀(jì)被發(fā)現(xiàn)以來，孤子理論始終是數(shù)學(xué)、物理學(xué)和通信等領(lǐng)域中重要的研究方向。光孤子的形成是光脈沖線性的時間域色散被非線性的自位相調(diào)制過程平衡。光孤子不僅僅是一個重要的科學(xué)研究方向，它同時具有重要的應(yīng)用前景，可能成為新一代的光纖通信傳輸模式和高速全光開關(guān)。本文首先詳細(xì)介紹了光孤子的基本理論、處理方法，光孤子通信的基本原理及其發(fā)展現(xiàn)狀，并分析了三階色散和五階飽和吸收等高階非線性效應(yīng)對被動鎖模光纖環(huán)形孤子激光器的穩(wěn)定性的影響。其次基于光孤子通信系統(tǒng)中孤子脈沖的傳輸所滿足的變系數(shù)非線
