Contribution
A novel technique combining Dammann optimization with metasurfaces to control all light parameters.
Findings
Metasurfaces enable control over polarization, phase, angular momentum, and spatial modes of light.
Three-dimensional generalized vortex beams can be generated using this technique.
Abstract
The ability to create complex three-dimensional structures of light is extremely challenging. Now, a technique combining Dammann optimization with metasurfaces has been developed, enabling control over all parameters, including polarization, phase, angular momentum, and spatial modes. The generation of three-dimensional generalized vortex beams can open new horizons for their applications in photonics.
