Researchers at Huazhong University of Science and Technology have demonstrated a fully tunable on-chip structured light meta-generator that maps multidimensional Poincare spheres. Using inverse-designed multimode meta-waveguides and multichannel coherent phase and amplitude control, the silicon photonic chip multiplexes higher-order waveguide modes and independently synthesizes polarization and spatial wavefronts, steering output to arbitrary points across polarization, OAM,
