光纤损耗对光孤子传输的影响

Influence of Fiber Loss on Optical Soliton Propagation

本文利用Bcklund变换研究了光孤子在单模光纤中的传输特性。研究结果表明,损耗使光孤子的脉宽按指数律exp(2 Γξ)扩展。在同一损耗下,孤子的速度越大,损耗对其强度衰减的影响越小。

Propagation characters of optical soliton in singlemode fiber is studied by using Backlund transformation in this paper.The results show that optical soliton pulse width broaden as exp(2Γξ)and the faster soliton speed is,the smaller soliton intensity decays because of fiber loss.
