大气湍流对双模量子态光场偏振特性的影响

摘要/Abstract

摘要： 数值分析了双模光子数态和相干态的部分相干高斯-谢尔模型光束传输通过non-Kolmogorov湍流的偏振特性；得到了双模量子态光场偏振度的具体表达形式。研究结果表明双模量子态光场在大气湍流中传输时，偏振度将受到湍流和探测光子数的影响；湍流的谱指数和内尺度越大或者湍流的折射率结构常数和湍流的外尺度越小，双模量子态光场受大气湍流的影响越小。此外，在双模光子数态光场中，两正交偏振模式上探测到的光子数相差越大，光场的偏振特性保持的越好，该结果与在双模相干态光场中得到的结果相反。

Abstract: Non-classical polarization properties of the quantum state of the two-mode partially coherent Gauss-shell model beam propagating through non-Kolmogorov turbulence are studied. The analytic equation for the polarization degree of the quantum state of the two-mode light field is obtained. Results show that the polarization fluctuations of the quantum state of the two-mode light field are dependent on the turbulence and the detection photon numbers；The polarization degree of the quantum state of the two-mode field gradually decrease. Furthermore, the bigger difference is on the two orthogonal polarization modes detected photon numbers, the better the polarization properties of the two-mode light field are maintained, which is contrary to the two-mode of the coherent state light field.
