随着集成光子学中元件数量的增加，复杂性的非线性扩展是阻碍大规模锁相激光阵列的主要障碍。在这里，我们发展了一种用于精确模式控制和非线性功率缩放的高维超对称形式。我们的超对称微激光阵列具有所有渐变耦合微环激光的锁相相干和同步功能--共同在基本横向超模中振荡--从而实现高辐射、小发散和单频激光发射，能量密度提高两个数量级。我们还论证了构造高辐射涡旋激光光束的可行性，充分利用光的空间自由度来提高激光器的性能。我们的方法为在经典和量子体系中设计大规模集成光子系统提供了一条途径。
The nonlinear scaling of complexity with the increased number of components in integrated photonics is a major obstacle impeding large-scale, phase-locked laser arrays. Here, we develop a higher-dimensional supersymmetry formalism for precise mode control and nonlinear power scaling. Our supersymmetric microlaser arrays feature phase-locked coherence and synchronization of all of the evanescently coupled microring lasers-collectively oscillating in the fundamental transverse supermode-which enables high-radiance, small-divergence, and single-frequency laser emission with a two-orders-of-magnitude enhancement in energy density. We also demonstrate the feasibility of structuring high-radiance vortex laser beams, which enhance the laser performance by taking full advantage of spatial degrees of freedom of light. Our approach provides a route for designing large-scale integrated photonic systems in both classical and quantum regimes.
