Figure 1. Principle and experimental demonstration of large-scale optical vortex array generation. a, Conventional Hermite–Gaussian (HG) to Laguerre–Gaussian (LG) mode conversion framework. b, Reconstructed HG–LG mode-conversion scheme introduced in this study, representing the first substantive revision in three decades. c, Integration of the reconstructed framework with multibeam interference to enable simultaneous generation of multiple optical vortices. d, Experimentally observed large-scale optical vortex array containing 3,070 phase-coherent vortices. The upper panel shows the cross-sectional intensity profile along the red arrow, and the green arrows indicate phase singularities.
