ABSTRACT We report a method to synthesize the complete range of arbitrary combinations of coherences independently in both the polarization and spatial degrees of freedom (DoFs) by utilizing energy conserving unitary and non-unitary transformations. We further demonstrate that starting from a fully spatially coherent and polarized field, one can achieve two light fields having any degree of mutual coherence, and remixing these fields can result in maximum visibility (unit) interference fringes irrespective of any degree of polarization of the mixed field. We believe that these results provide new insight and may contribute significantly towards the ongoing explorations on optical coherence and its applications.

偏振和空间自由度中的光学相干工程

摘要 我们报告了一种方法，通过利用能量守恒的酉变换和非酉变换，在极化和空间自由度 (DoF) 中独立地合成完整范围的相干性任意组合。我们进一步证明，从完全空间相干和偏振场开始，可以实现两个具有任何相互相干程度的光场，并且重新混合这些场可以导致最大可见度（单位）干涉条纹，而不管混合的偏振度如何场地。我们相信这些结果提供了新的见解，并可能对正在进行的光学相干性及其应用的探索做出重大贡献。
