摘要/Abstract

摘要： 利用Bäcklund变换研究了光孤子在单模光纤中的传输特性。结果表明,损耗使光孤子的脉宽按指数律exp(2Γξ)扩展。光孤子的速度越大,损耗对其强度衰减的影响越小。

关键词: 光纤损耗, 光孤子, Bä, cklund变换

Abstract: Propagation characters of optical soliton in single-mode fiber is studied by using Bäcklund transformation. The results show that optical soliton pulse width broaden as excp(2Γξ) and the faster soliton speed is, the smaller soliton intensity decays because of fiber loss.

Key words: fiber loss, optical soliton communication, Bäcklund transformation
