非经典光源常用于量子密码学等领域。为了获得可调的、高性能的非经典光源，我们需要找到一个合适的量子系统，而非传统光子阻挡效应是一个很好的方法。其中，相关函数和平均光子数是探索非经典光源性能的重要工具。目前，虽然已有大量研究利用非传统光子阻挡效应制作非经典光源，但大多数研究讨论的是如何制作好的单光子光源，很少有研究考虑调整其亮度和类型。基于以上考虑，本文提出了一种构造可调高阶光子阻挡现象的方法。我们利用两个场同时驱动原子和腔，并将原子驱动强度与腔驱动强度之比定义为驱动比。通过调节驱动比，可以使非经典光源的类型和平均光子数从单光子阻塞不断地调整到高阶光子阻塞效应。这些发现为未来可调非经典光源的生产提供了新的途径。
Non-classical light sources are often used in quantum cryptography and other fields. To obtain adjustable, high-performance non-classical light sources, we need to find a suitable quantum system, to which non-traditional photon blocking effect is a good method. Among them, the correlation function and the mean number of photons are important tools to explore the performance of non-classical light sources. At present, although a large number of studies have been made to use the non-traditional photon blocking effect to produce non-classical light sources, most of the studies discussed how to produce good single-photon sources, rarely studies consider adjusting the brightness and the types of it. Based on the above considerations, this paper proposes a method to construct an adjustable high-order photon blocking phenomenon. We employed the two field to drive the atom and the cavity simultaneously and define the ratio of the atomic drive strength to the cavity drive strength as the drive ratio. By adjusting the drive ratio, the types and the mean photon number of non-classical light sources can be tuned constantly from single photon blocking to high-order photon blocking effect. These findings can provide a new way for the future production of adjustable non-classical light sources.
