The spatial second-order interference of two independent pseudothermal light beams in a Hong-Ou-Mandel interferometer is studied experimentally and theoretically. The similar cosine modulation in the second-order coherence function as the one with entangled-photon pairs in a Hong-Ou-Mandel interferometer is observed. Two-photon interference based on Feynman's path integral theory is employed to interpret the results. The experimental results and theoretical simulations agree with each other very well.
对洪-欧-曼德尔干涉仪中两束独立赝热光的空间二阶干涉进行了实验和理论研究。观察到二阶相干函数中出现了与洪-欧-曼德尔干涉仪中纠缠光子对类似的余弦调制。基于费曼路径积分理论的双光子干涉被用来解释这些结果。实验结果与理论模拟非常吻合。
