放大耦合激光器阵列的辐射率一直是光子学中的一个长期挑战。在这项研究中，我们证明了超光速的概念-在高能物理学中发展的理论框架-可以战略性地用于光学来解决这个问题。在这方面，实现了超对称激光器阵列，其能够以稳定的方式仅以其基横模发射。我们的研究结果不仅为设计集成激光器中按比例增加辐射的新方案铺平了道路，而且在更基本的层面上，可以揭示非厄米性和超对称性之间有趣的协同作用。
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.
