A higher-dimensional supersymmetry formalism was developed for precise mode control and nonlinear power scaling in integrated photonics, leading to high-radiance, small-divergence, and single-frequency laser emission in supersymmetric microlaser arrays. This approach also demonstrates the feasibility of structuring high-radiance vortex laser beams, enhancing laser performance by utilizing spatial degrees of freedom of light, and providing a route for designing large-scale integrated photonic systems in both classical and quantum regimes.
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.
