单模光纤中的光孤子通信研究现状及展望

通过光纤色散对光脉冲的展宽，光纤非线性中自相位调制对光脉冲展宽及啁啾生成的分析，利用非线性薛定谔方程详细阐明了光孤子的形成及其传输的基本原理，对光孤子通信的损耗，放大、光弧子间的相互作用以及Ｇｏｒｄｏｎ－Ｈａｕｓ限制等关键技术及难点进行了讨论，并对光孤子通信系统及有关的近期发展进行了介绍。

The Sate of Art of Optical Soliton Communication in Monomode Optical Fibers

At present, optical soliton communication in monomode optical fibers becomes a hot point in communication, and had extensive application prospects. In this paper, the principles about the formation and propagation of optical soliton is presented. The key technology and difficulties of optical soliton communication are discussed. The systems and the recent development of optical soliton communication are reviewed.
