Abstract

Beyond one-dimensional optical singularity topologies, we demonstrate zero-dimensional (point) and two-dimensional (sheet) singularities. We engineer phase and polarization sheet singularities through inverse-design, by maximizing the field phase gradient, and demonstrate metasurface-enabled realizations of each.
