初始啁啾对光孤子压缩态的影响

Impacts of the Initial Chirp on Soliton Squeezed State

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初始啁啾对光孤子压缩比的影响。数值结果表明，初始正啁啾在初始一定距离范围内能减小压缩比，理想光孤子的压缩效果最好。

Based on the linearization approximation, nonlinear Schrdinger equation is quantized, the influences of the initial chirp on soliton squeezing ratio was studied by using back propagation method. Numerical results show that the squeezing ration decreases at some initial distance when the chirp is positive and the squeezing was the best if the pulse is ideal fundamental soliton.
