Originally developed in the context of quantum field theory, the concept of supersymmetry can be used to systematically design a new class of optical structures. In this work, we demonstrate how key features arising from optical supersymmetry can be exploited to control the flow of light for mode-division multiplexing applications. Superpartner configurations are experimentally realized in coupled optical networks, and the corresponding light dynamics in such systems are directly observed. We show that supersymmetry can be judiciously used to remove the fundamental mode of a multimode optical structure while establishing global phase-matching conditions for the remaining set of modes. Along these lines, supersymmetry may serve as a promising platform for versatile optical components with desirable properties and functionalities.
最初在量子场论的背景下发展起来的超对称性概念，可以用于系统地设计一类新的光学结构。在这项工作中，我们展示了如何利用超对称性产生的关键特征来控制光的流动，以实现模式分割复用应用。在耦合光网络中实验实现了超伴配置，并直接观察到了此类系统中的相应光动力学。我们表明，可以明智地使用超对称性来去除多模光学结构的基本模式，同时为其余模式集建立全局相位匹配条件。沿着这些思路，超对称性可以作为一个有前途的平台，用于具有理想特性和功能的多功能光学元件。
