We present an experimental technique that can accurately measure the high-order photon correlations of various light fields based on double Hanbury Brown–Twiss scheme. The system consists of four conventional binary response single-photon counting modules which are non-photon-number-resolving detectors. We theoretically analyze the effects of the experimental conditions on the high-order photon correlations of coherent, chaotic thermal, Fock and squeezed vacuum states with considering the overall efficiency and background noise. In experiment, we determine the proper resolution time from 2 9 = 512 ns to 2 11 = 2048 ns and counting rate from 10 kc s −1 to 100 kc s −1 for characterizing the exact second-, third- and fourth-order photon correlations of chaotic thermal state. At complete time delays, we also observe the third- and fourth-order photon correlations of chaotic thermal state, with the maximum high-order correlation values of 5.99 ...

通过两次Hanbury Brown-Twiss测量获得高阶光子相关性

我们提出了一种实验技术，它可以基于双重Hanbury Brown-Twiss方案准确测量各种光场的高阶光子相关性。该系统由四个常规的二进制响应单光子计数模块组成，它们都是非光子数解析探测器。我们从理论上分析了实验条件对相干，混沌热，Fock和压缩真空状态的高阶光子相关性的影响，同时考虑了整体效率和背景噪声。在实验中，我们确定从2 9 = 512 ns到2 11 = 2048 ns的正确分辨时间，从10 kc s -1到100 kc s -1的计数率来表征确切的二阶，三阶和四阶光子混沌热状态的相关性。在完全延迟的情况下，
