Abstract
Orbital angular momentum, as an important spatial degree of freedom of light, has prompted various promising applications. The recently proposed generalized vortex beams may further enhance the flexibility by utilizing customer-defined angular phase gradients, enabling intuitive graphic representation of mathematical operations and other interesting functionalities. Here, based on Dammann optimization, we propose and demonstrate a three-dimensional generalized vortex beam array using a single-layer metasurface, with all-parameter modulation including polarization, phase, angular momentum, and stereoscopic space. Furthermore, simultaneous vectorial modulation within each order can be endowed through joint…
