在线性近似条件下,量子化了非线性薛定谔方程,用后向传播法数值求解了孤子源啁啾对量子光孤子的影响。数值求解结果表明,孤子源正啁啾在初始一定距离范围内能减小压缩比。 Under the condition of linear approximation, the nonlinear Schrödinger equation is quantized, and the effect of the chirp of the soliton on the quantum soliton is solved by the back propagation method. The numerical results show that the positive chirp of the soliton source can reduce the compression ratio within a certain initial distance range.
