a Schematic of the desired phase modulation Ω±x for even |m〉even and odd |m〉odd CVB modes. b SEM images of the fabricated sample. c Experimental setup. LP linear polarizer, HWP half wave plate, MS metasurface. d Experimentally tested results for demonstrating the separation of the even and odd CVBs with topological charges m = 1, −1, and 2. The presence of the white double arrows at the bottom indicate that the resulting field distributions are obtained by applying a horizontal polarizer.
