Abstract

From quantum point of view, Hanbury Brown-Twiss effect is a result of constructive-destructive two-photon interference. There should be no Hanbury Brown-Twiss effect if there was no two-photon interference. In this paper, we observed Hanbury Brown- Twiss effect in a specially designed experiment, in which two-photon interference is impossible by keeping only one two-photon probability amplitude in the experimental scheme. However, our experimental results can still be interpreted by Glauber's quantum optical coherence theory. The researches in our paper are helpful to understand the physics of the second-order coherence of light, especially the physics of Hanbury Brown-Twiss effect.

摘要

从量子观点来看，汉布利·布朗-图维斯特效应是相长相消的双光子干涉的结果。如果不存在双光子干涉，就不会有汉布利·布朗-图维斯特效应。在本文中，我们在一个特殊设计的实验中观察到了汉布利·布朗-图维斯特效应，在这个实验方案中，通过保持实验方案中只有一个双光子概率幅，双光子干涉是不可能的。然而，我们的实验结果仍然可以用格劳伯的量子光学相干理论来解释。本文的研究有助于理解光的二阶相干物理，特别是汉布利·布朗-图维斯特效应的物理。
