偏振相干定理的实验观察

Experimental observation of polarization coherence theorem

Bhaskar Kanseri, Sethuraj K. R

摘要:

对于光场,在不同时空点处的波动电场分量之间的相关性的表现被称为相干性,而在单个时空点处的正交电场分量之间出现的这些相关性被称为偏振。在这方面,一个自然的问题是:一致性和两极分化是如何相互关联的?最近,已经提出了一个紧密的等式P^2=V^2+D^2,即“偏振相干定理”(PCT),将偏振P与干涉可见度V(相干性的度量)和可分辨性D(哪个路径信息的度量)联系起来[Optica 4,1113(2017)]。我们在这里报告的直接观察PCT的经典光场使用马赫-曾德尔干涉仪与合成源一起产生一个完整的全域度的偏振。我们的实验演示可以激励正在进行的实验努力,探索隐藏的连贯性和互补性功能。

英文摘要:

For light fields, the manifestation of correlations between fluctuating electric field components at different space-time points is referred to as coherence, whereas these correlations appearing between orthogonal electric field components at single space-time point are referred to as polarization. In this context, a natural question is: how coherence and polarization are interconnected? Very recently, a tight equality P^2=V^2+D^2 namely the "polarization coherence theorem" (PCT) connecting polarization P with interference visibility V (measure of coherence) and distinguishability D (measure of which-path information) has been proposed [Optica 4, 1113 (2017)]. We here report a direct observation of PCT for classical light fields using a Mach-Zehnder interferometer along with a synthesized source producing a complete gamut of degrees of polarizations. Our experimental demonstration could motivate ongoing experimental efforts towards probing the hidden coherences and complementarity features.
