Abstract

Phase-dependent photon statistics is observed in the mixed field of a narrow band two-photon source and a coherent field. At a certain phase, the nonclassical effect of photon antibunching occurs while at another the photon bunching effect appears. Furthermore, we observed a novel nonclassical phenomenon that exhibits more complex structure. The different features in photon statistics are attributed to a two-photon interference effect.

摘要

在窄带双光子源与相干场的混合场中观测到了相位相关的光子统计特性。在某一相位时，会出现光子反聚束的非经典效应，而在另一相位时则会出现光子聚束效应。此外，我们还观测到了一种呈现出更复杂结构的新型非经典现象。光子统计中的不同特征归因于双光子干涉效应。
