In quantum optics and its applications, there is an urgent demand for photon-number resolving detectors. Recently, there appeared multi-pixel counters (MPPC) that are able to distinguish between 1,2,..10 photons. At the same time, strong coupling between different pixels (crosstalk) hinders their photon-number resolution. In this work, we suggest a method for `filtering out' the crosstalk effect in the measurement of intensity correlation functions. The developed approach can be expanded to the analysis of higher-order intensity correlations by using just a single MPPC.
在量子光学及其应用领域，对光子数分辨探测器有着迫切需求。最近，出现了能够区分1、2、……10个光子的多像素计数器（MPPC）。与此同时，不同像素之间的强耦合（串扰）阻碍了它们的光子数分辨率。在这项工作中，我们提出了一种在强度关联函数测量中“滤除”串扰效应的方法。所开发的方法仅使用单个MPPC就可以扩展到高阶强度关联的分析。
