a Optical microscope image of the employed WSe₂ monolayer. The white dotted line highlights the boundaries. b, c SH spectra of the WSe₂ monolayer for ∆t > τ (b) and ∆t ≈ 0 (c). d–f The top row shows the phase distribution for different circular polarizations of the incident field. The bottom row shows optical images of the metasurfaces (left) and SEM images of the central areas of the structures (right) for d beam deflection, e Gaussian-to-vortex beam switching, and f topological charge switching, respectively.
