初始振幅和波形对量子光孤子的影响

Impacts of the Initial Amplitude and Wave Shape on Quantum Soliton

在线性近似条件下，量子化了非线性薛定锷方程，用后向传播法数值求解了初始振幅和波形对光孤子压缩比的影响。数值结果表明，增大初始振幅在初始一定距离范围内能减小压缩比。

Based on the linearization approximation, nonlinear Schrodinger equation is quantized . The influences of the inintial amplitude and wave shape on soliton squeezing ratio is studied by using backpropagation method. Numerical results show that the squeezing ratio decrease at some initial distance when the amplitude increase and the squeezing was best if pluse wave shape near fundamental soliton.
