单模光纤中光脉冲对的聚合与分裂

Merging and Splitting of Pulses in Optical Fibers

对于双光脉冲在非线性单模光纤中传输问题 ,通过数值求解非线性Schr dinger方程 ,发现脉冲的分裂、聚合现象 讨论了不同入射光强度下 ,分裂、聚合的特点 ,以及产生分裂、聚合的物理机制 对聚合后光脉冲的频谱进行了分析 ,除了观察到与入射脉冲相同的中心频带外 。

It is found the merging and splitting of optical pulses by solving nonlinear Schrdinger equation numerically for the problem of transmission in nonlinear single-mode optical fibers. It is discussed the trait and the physical principle of the merging and splitting of the pulses under the different intensities and analyze the pulse spectrum when pulses merging. There is a spectral band with the same center-frequency as that of the incidence pulse and two wider sidebands.
