Abstract

Optical beams with Orbital Angular Momentum (OAM) can potentially be used to probe forbidden transitions. However, the size of the vortex beam has to be comparable to that of an atom, molecule or an artificial atom. We propose and demonstrate a de-magnifying hyperlens allowing reducing the size of the vortex beam to the nanometer scale.
