有绝热放大的色散缓变光纤中孤子的有效压缩

Efficient soliton compression in a dispersion-decreasing fiber with adibatic amplification

提出了一种快速绝热压缩光孤子的新方法，即用色散缓变光纤和绝热放大两者组合压缩光孤子，利用变分法求解了光孤子在这种组合系统中传播所满足的非线性Schrodinger方程；在绝热情形下，获得了孤子脉宽演化的解析表达式，解析结果与数值模拟符合甚好。

A new proposal for adiabatic soliton cmpression that uses an exponentially dispersion - decreasing fiber amplifier is presented. An explicit analytical approximate solution to the evolution equahon for the case of adiabatic compression is obtained by means of variational technique. The obtainedresults are in good agreement with numerical simulations.
