光学相位共轭中剩余三阶色散不利于共轭孤子的稳定传输,导致孤子脉冲具有更大的时间抖动.本文提出在传输线末采用具有正三阶色散的色散位移光纤补偿光学相位共轭中的剩余正三阶色散.数值结果证明了其可行性.同时也分析其补偿的物理机制.
The remaining third-order dispersion in the optical phase conjugation is not conducive to the stable transmission of the conjugate soliton, resulting in more time jitter in the soliton pulse. In this paper, we propose to use dispersion-shifted optical fiber with positive third-order dispersion to compensate the residual in the optical phase conjugation Positive third-order dispersion.The numerical results prove its feasibility, and also analyze the physical mechanism of its compensation.
