Among the best known quantities obtainable from photon correlation measurements are the g(m) correlation functions. Here, we introduce a new procedure to evaluate these correlation functions based on higher-order factorial cumulants CF,m that integrate over the time dependence of the correlation functions, that is, summarize the available information at different time spans. In a systematic manner, the information content of higher-order correlation functions as well as the distribution of photon waiting times is taken into account. Our procedure greatly enhances the sensitivity for probing correlations and, moreover, is robust against a limited counting efficiency and time resolution in experiment. It can be applied even in case g(m) is not accessible at short time spans. We use the new evaluation scheme to analyze the photon emission of a plasmonic cavity coupled to a single quantum dot. We derive criteria that must hold if the system can be described by a generic Jaynes–Cummings model. A violation of the criteria can be explained by the presence of an additional excited quantum dot state.

高阶光子统计作为揭示等离子体腔中隐藏激发态的新工具

从光子相关测量中获得的最著名的量是g ( m )相关函数。在这里,我们引入了一个新的程序来评估这些基于高阶阶乘累积量C F 的相关函数,m整合相关函数的时间依赖性,即总结不同时间跨度的可用信息。系统地考虑了高阶相关函数的信息内容以及光子等待时间的分布。我们的程序大大提高了探测相关性的灵敏度,而且,在实验中对有限的计数效率和时间分辨率具有鲁棒性。即使在g ( m )的情况下也可以应用在短时间内无法访问。我们使用新的评估方案来分析耦合到单个量子点的等离子体腔的光子发射。如果系统可以用通用 Jaynes-Cummings 模型描述,我们推导出必须遵守的标准。违反标准可以通过存在额外的激发量子点状态来解释。
