用量子力学方法处理光纤孤子的传输问题。用类Kerr介质的微观模型及色散关系,导出了含修正项的量子非线性薛定谔方程;求出其微扰解并且研究了修正项对压缩的影响。结果表明:三阶色散对压缩无影响,而立方导数项则使压缩变浅。In this paper, we treat optical soliton propagation with quantum method. We derive the quantum nonlinear Schrodinger equation (QNSE) with corrections by using the micro model of a Kerr-like medium and dispersion relation. We also find the perturbation solution of thisequation and study the influence of corrections on squeezing. The result indicates that thethird-order dispersion has no influence on squeezing and the term in ?/(?τ)(φ+φ2) makes theamount of squeezing decrease.
