摘要
基于线性量子化理论和热库模型量子化了含损耗的非线性Schrdinger方程并给出了孤子脉冲在含损耗的光纤中传输的压缩比计算式,用数值计算方法分析了不同光纤损耗对孤子最小压缩比的影响以及在此模型下不同输入振幅的孤子脉冲其最小压缩比与传输距离的关系。
Based on the linear quantum theory and thermal reservoir model, we quantized the non-linear Schrdinger equation with fiber loss and derive the squeezing ratio formula. We analyzed the different coefficient of the loss which leads to the effect of the squeezed soliton. At the same time, we discuss the relation between the minimal squeezing ratio and the transmitted length along the fiber with the different soliton amplitude.
