We present an in principle lossless sorter for radial modes of light, using accumulated Gouy phases. The experimental setups have been found by a computer algorithm, and can be intuitively understood in a geometric way. Together with the ability to sort angular-momentum modes, we now have access to the complete two-dimensional transverse plane of light. The device can readily be used in multiplexing classical information. On a quantum level, it is an analog of the Stern-Gerlach experiment-significant for the discussion of fundamental concepts in quantum physics. As such, it can be applied in high-dimensional and multiphotonic quantum experiments.
我们提出了一种基于累积古斯相位的光的径向模式的理论上无损耗分类器。实验装置是通过计算机算法找到的，并且可以通过直观的几何方式来理解。加上分类角动量模式的能力，我们现在可以访问光的完整二维横向平面。该设备可以方便地用于复用经典信息。在量子水平上，它是斯特恩-格拉赫实验的模拟-对于讨论量子物理学中的基本概念具有重要意义。因此，它可以应用于高维和多光子量子实验。
