Abstract
In a recent article Babiker et al. (2024) claim that cylindrical vector beams (CVBs), also referred to as higher-order Poincaré (HOP) beams, possess optical chirality densities which exhibit ‘superchirality’. Here we show that, on the contrary, CVBs possess less optical chirality density than a corresponding circularly polarized scalar vortex beam and that the ‘superchiral’ results are nonphysical. We also identify a number of issues concerning the derivation and general theory presented.
