独立光子源间的宏欧曼德尔干涉（HOM）是量子信息处理的基本模块。以往的HOMI-IPS实验都是在时域进行的，忽略了干涉过程中的光谱信息。在这里，我们研究了HOMI-IPS在光谱域使用最近开发的快速光纤光谱仪，并演示了HOM干涉过程中的光谱分布在两个预示单光子源，两个热源。该实验不仅可以从谱域的角度加深我们对HOMI-IPS的理解，而且还提供了一种使用光谱工程源测试HOMI-IPS理论预测的工具。(C)2015美国光学学会
Hong-Ou-Mandel (HOM) interference between independent photon sources (HOMI-IPS) is the fundamental block for quantum information processing. All the previous HOMI-IPS experiments were carried out in time-domain, however, the spectral information during the interference was omitted. Here, we investigate the HOMI-IPS in spectral domain using the recently developed fast fiber spectrometer, and demonstrate the spectral distribution during the HOM interference between two heralded single-photon sources, and two thermal sources. This experiment not only can deepen our understanding of HOMI-IPS from the viewpoint of spectral domain, but also presents a tool to test the theoretical predictions of HOMI-IPS using spectrally engineered sources.
