We reported the second- and third-order temporal interference of two non-degenerate pseudo-thermal sources in a nitrogen-vacancy center (NV). The relationship between the indistinguishability of source and path alternatives is analyzed at low temperature. In this article, we demonstrate the switching between three-mode bunching and frequency beating effect controlled by the time offset and the frequency difference to realize optical demultiplexer. Our experimental results suggest the advanced technique achieves channel spacing and speed of the demultiplexer of about 96% and 17 ns, respectively. The proposed demultiplexer model will have potential applications in quantum computing and communication.
我们报道了在氮空位中心（NV）中两个非简并伪热光源的二阶和三阶时间干涉。在低温下分析了光源和路径选择的不可区分性之间的关系。在本文中，我们展示了由时间偏移和频率差控制的三模聚束和频率拍频效应之间的切换，以实现光解复用器。我们的实验结果表明，该先进技术实现的解复用器的通道间距和速度分别约为96%和17纳秒。所提出的解复用器模型将在量子计算和通信中具有潜在应用。
