在有损耗光纤中双孤子的传播问题

Double Solitons Propagate in Lossy Optical Fiber

本文研究了光纤的损耗时双孤子的间隔r的影响。本文导出了r随t变化的公式,通过数值计算表明,当r<10w时,w为孤子的半宽度,损耗对r的变化有明显的影响。

In this paper, the effect of loss rate of fiber to the distance r between two solitons is considered, the formulae for computing the variation of r are obtained, the numerical computational results prove that if r<10w, w is half-width of a soliton, then r is affected obviously by loss rate.
