Compton散射对光纤中孤子压缩态传输的影响

Influences of Compton scattering on soliton squeezed state transmission in fiber

应用非线性量子理论和修正非线性Schr(?)dinger方程,研究了多光子非线性Compton散射对孤子压缩态传输的影响,给出了孤子传输的压缩比。研究发现,在理想一阶孤子附近,随振幅的增大,散射能使孤子的最小压缩比更小,即能得到更大的孤子压缩态。随损耗的增大,压缩态呈较缓慢的减小。在相同损耗情况下,随振幅的增大,得到的最小压缩比所需传输距离较散射前短一些。

Using the nonlinear quantum theory and revised Schrodinger equation, the influences of the multi-photon nonlinear Compton scattering on the propagation of the soliton squeezed state in the fiber are studied, and the squeezing ratio of the soliton propagation is given out. The results show that near the ideal first-order soliton, the scattering can make the smallest soliton squeezed ratio with the increase of the soliton pulse amplitude, that is to say the larger soliton squeezed state can be gotten. With the increase of the loss, the squeezed degree of the squeezed state slowly decreases. When the loss is same, the transmission distance to get the smallest soliton squeezed ratio is shorter than that before the scattering with the increase of the soliton pulse amplitude.
