Ultrathin plasmonic chiral phase plate

Not Accessible

Your library or personal account may give you access

Abstract

A thin free-standing gold membrane with complex plasmonic structures engraved on both sides is shown to perform as an ultrathin phase plate. Specifically, we demonstrate the generation of a far-field vortex beam propagating at a desired angle. The angular momentum of the beam is generated by the groove helicity, together with the geometric phase arising from a plasmonic spin–orbit interaction. The radial chirp of the back-side structure is used to modify the emission angle via a specific momentum matching condition.
