半经典场论模型中光的时间相干长度

Temporal coherence length of light in semiclassical field theory models

Borys Jagielski, Johanne Lein, Arnt Inge Vistnes

摘要:

下面的工作是由与波粒二象性和光子概念有关的概念问题激发的。两个简单的经典模型的辐射从个别发射器进行了比较,一个基于正弦随机phasejumps,另一个基于脉冲序列。针对不同数量的发射器计算和信号。重点在于通过时间相干函数和时间相干长度量化最终信号的统计特征。我们展示了如何使用这些功能来实验区分模型。我们还指出了时间相干长度的定义中的模糊性。

英文摘要:

The following work is motivated by the conceptual problems associated with the wave-particle duality and the notion of the photon. Two simple classical models for radiation from individual emitters are compared, one based on sines with random phasejumps, another based on pulse trains. The sum signal is calculated for a varying number of emitters. The focus lies on the final signal's statistical features quantified by means of the temporal coherence function and the temporal coherence length. We show how these features might be used to experimentally differentiate between the models. We also point to ambiguities in the definition of the temporal coherence length.
