High-capacity millimetre-wave communications with orbital angular momentum multiplexing. [PDF]
Nat Commun, 2014 One property of electromagnetic waves that has been recently explored is the ability to multiplex multiple beams, such that each beam has a unique helical phase front. The amount of phase front 'twisting' indicates the orbital angular momentum state number, and beams with different orbital angular momentum are orthogonal.

Polarization-Encrypted Orbital Angular Momentum Multiplexed Metasurface Holography [PDF]
ACS Nano, 2020 Metasurface holography has the advantage of realizing complex wavefront modulation by thin layers together with the progressive technique of computer-generated holographic imaging. Despite the well-known light parameters, like amplitude, phase, polarization and frequency, the orbital angular momentum (OAM) of a beam can be regarded as another degree of

Phyllotaxis-inspired nanosieves with multiplexed orbital angular momentum [PDF]
eLight, 2021 AbstractNanophotonic platforms such as metasurfaces, achieving arbitrary phase profiles within ultrathin thickness, emerge as miniaturized, ultracompact and kaleidoscopic optical vortex generators. However, it is often required to segment or interleave independent sub-array metasurfaces to multiplex optical vortices in a single nano-device, which in ...
