摘要
从非线性薛定谔方程出发,研究了初始非线性频率啁啾对二阶孤子脉冲传输行为的影响。发现二阶孤子脉冲的分裂现象,并分析了产生分裂的原因,同时得出了分裂产生的阈值条件。对于初始非线性啁啾脉冲,初始入射脉冲的啁啾参数不同时,产生分裂的现象也不同,并讨论了其物理机制。
It is discussed the influence of nonlinear frequency chirp to the transmission of 2nd-soliton in optical fibers by solving nonlinear Schrodinger equation. Splitting of 2nd-soliton is found and the reason of the splitting is analysed and then threshold value of splitting is gotten. When parameters of the initial pulse vary, the phenomenon of the splitting is difference, and the physical mechanism is discussed.
