Super-chirality of paraxial higher order Poincare modes

We demonstrate that higher order Poincare modes of order m are super-chiral, displaying enhancement factors proportional to $m$ and $m^2$ in their helicity/chirality. With m having arbitrarily large integer values, such modes, in principle, possess unlimited super-chirality. These findings pave the way to applications, including the strong enhancements of optical interactions with chiral matter. The work indicates considerable flexibility in controlling the helicity of any higher order paraxial twisted light mode and it incorporates a very wide range of physical scenarios.
