Fig. 4: Parity and topological charge demultiplexing of multiple CVBs.
From: Optical vectorial-mode parity Hall effect: a case study with cylindrical vector beams
a The spatial intensity distributions of CVBs with topological charge from m = 0 to m = 6. b The arrangements of elliptical resonators on the metasurface and the SEM image of the fabricated sample. c Schematic of distributed demultiplexed results of CVBs with both topological charge and parity, denoted by (m, parity). d Experimentally tested results of CVB demultiplex up to 14 channels in the experiment with the demultiplexed two parities and topological charges from m = 0 to m = 6. The white-arrows pattern in each subgraph indicates the polarization distributions of the corresponding CVB.
