摘要
用一对平衡零拍探测器分别替代HBT(Hanbury-Brown-Twiss)实验中的单光子探测器,构成了一个modified-HBT干涉仪。介绍了基于modified-HBT干涉仪的光场二阶关联函数测量原理以及步骤,着重讨论了测量过程中对暗噪声的处理。基于理论分析,利用此干涉仪同时记录和统计了光场两空间分离模式的正交分量信息,实现了对光学参量振荡器输出的平移压缩态光场二阶关联函数的测量以及光子统计特性的表征。对于振幅压缩光,在特定的平移参量下,其二阶关联函数值小于1,表明光子呈现反聚束效应;而相位压缩光的二阶关联函数值总是大于1,光子呈现聚束效应。利用双光子干涉理论对测量到的平移压缩态光场的光子统计特性进行了解释,为理解压缩光的光子统计特性提供了参考。
Abstract
By replacing the single-photon detector in a HBT (Hanbury-Brown-Twiss) experiment by a pair of homodyne detectors, we constructe a modified-HBT interferometer. We introduce the principle and procedure for the measurement of the second-order correlation function of light field based on the modified-HBT interferometer, and maily discuss the substraction of dark noises in the process. Based on the theoretical analysis, we realize the measurement of the second-order correlation function of displaced squeezed light output from an optical parametric osciallator and the characterization of photon statistics features through the simultaneous record and statistics of the quadrature information collected by the above interferometer for two spatially separated mode of light field. For amplitude squeezed light, its second-order correlation functional value is less than 1 under a specific displacement, indicating photon anti-bunching. In contrast, for phase squeezed light, the second-order correlation functional value is always greater than 1, indicating photon bunching. The properties of photon statistics for displaced squeezed light are explained from a viewpoint of two-photon interference, which can provide a reference for understanding the photon statistics features of squeezed light.
