摘要:

在这项工作中,我们研究了探测单光子和多光子相干态的InGaAs/InP正弦门控和自由运行的单光子雪崩二极管的概率。因此,我们得出结论,多光子态探测不能被看作是单个单光子态吸收的独立事件。然而,如果更多的状态是单光子和双光子,那么独立模型是允许的。我们的结论是,物理过程必须发生在二极管结构,确定的相关性时,几个光子被同时吸收。我们提出了两个模型,我们可以用来描述光子相互作用的结构。依赖模型基于在n光子状态下不幸检测到第(n-1)个光子时检测到第n个光子的概率的增加/减少,并且具有良好的物理基础;经验模型提供了简单而准确的经验关系。

英文摘要:

In this work we investigate the probabilities of detecting single- and multi-photon coherent states on InGaAs/InP sine-gated and free-run single-photon avalanche diodes. As a result, we conclude that multi-photon state detection cannot be regarded as independent events of absorption of individual single-photon states. However, if a greater number of states are one- and two-photon, then an Independent model is permissible. We conclude that physical processes must occur in the diode structure, determining the correlation when several photons are absorbed simultaneously. We present two models that we can use to describe photon interactions in a structure. The Dependent model is based on an increase/decrease in the probability of detecting an n-th photon upon an unfortunate detection of an (n-1)-th photon in an n-photon state and is well physically grounded; The Empirical model offers a simple and accurate empirical relationship.
