摘要

基于受激布里渊散射三波耦合方程组，应用小信号分析，研究了高非线性光纤的信号光脉冲提前及形变。结果表明，光纤中信号光脉冲的时间提前量在一定范围内随着输入信号光功率和传输距离的增长而近似线性增长，同时脉冲压缩程度加强；在相同条件下，非线性光纤比普通单模光纤的时间提前量更大，在50 m长的高非线性光纤中，信号光能量在50 mW时实现了203 ns的时间提前量和较小的脉冲形变。高非线性光纤的快光提前效率显著提高，脉冲形变显著减小。研究结果对快光的实现和应用具有参考意义。

Abstract

Based on the three coupled wave equations of stimulated Brillouin scattering and under the condition of small-signal model

the time advancement and pulse distort of fast light in high nonlinear optical fiber were investigated. The results indicate that the time advancement linearly increases and pulse compression becomes larger with the increasing of the input signal power and the transmission distance in optical fiber. Under the same condition

the time advancement occurred in high nonlinear optical fiber is larger than that in single mode fibers

and the maximum advancement of 203 ns as well as small pulse distort are achieved in high nonlinear fiber at the signal power of 50 mW and the fiber length of 50 m. The efficiency of time advancement of fast light in high nonlinear fiber is significantly improved and the pulse deformation is obviously decreased. The research results provide reference for the implementation and application of fast light.
