Full-Dimensional Spatial Light Meta-modulators

open access: yes, 2022
The full-dimensional spatial light meta-modulator requires simultaneous, arbitrary and independent manipulation of spatial phase, amplitude, and polarization. It is an essential step towards harnessing complete dimensional resources of light.
