摘要
首次报道孤子光纤中拉曼自频移效应的研究结果,对满足孤子光纤色散关系条件时含损耗、拉曼延迟效应的广义非线性薛定谔方程进行了微扰分析,求得了拉曼自频移关系表达式,发现改变光纤几何参数可以有效地控制孤子拉曼自频移。
The Raman soliton self-frequency shift in soliton fiber is investigated by meansof analyzing Perturbatively quasinonlinear Schrodinger equation including fiber loss andRaman delayed nonlinear effect.It is found that the self-frequency shift in soliton fiber ismuch small comparing to that in conventional fiber, and it can be controlled by adjustingthe fiber structure Parameters.
