Scaling up the radiance of coupled laser arrays has been a long-standing challenge in photonics. In this study, we demonstrate that notions from supersymmetry-a theoretical framework developed in high-energy physics-can be strategically used in optics to address this problem. In this regard, a supersymmetric laser array is realized that is capable of emitting exclusively in its fundamental transverse mode in a stable manner. Our results not only pave the way toward devising new schemes for scaling up radiance in integrated lasers, but also, on a more fundamental level, could shed light on the intriguing synergy between non-Hermiticity and supersymmetry.
扩大耦合激光阵列的辐射度一直是光子学领域长期存在的挑战。在本研究中，我们证明了超对称（高能物理中发展起来的一个理论框架）的概念可以在光学中战略性地用于解决这个问题。在这方面，实现了一种超对称激光阵列，它能够以稳定的方式仅在其基横模下发射。我们的结果不仅为设计集成激光器中扩大辐射度的新方案铺平了道路，而且在更基本的层面上，可能会揭示非厄米性和超对称之间有趣的协同作用。
