“…With OAM-DM, the on and off states of each OAM mode can represent either a "1" or a "0", so that the two-bit set of {00, 01, 10, 11} can be mapped on the multiplexed modes {00, 0 1 , 0 0, 0 1 }.

Orbital angular momentum (OAM) has aroused a widespread interest in many fields, especially in telecommunications due to its potential for unleashing new capacity in the severely congested spectrum of commercial communication systems. Beams carrying OAM have a helical phase front and a field strength with a singularity along the axial center, which can be used for information transmission, imaging and particle manipulation. The number of orthogonal OAM modes in a single beam is theoretically infinite and each mode is an element of a complete orthogonal basis that can be employed for multiplexing different signals, thus greatly improving the spectrum efficiency. In this paper, we comprehensively summarize and compare the methods for generation and detection of optical OAM, radio OAM and acoustic OAM. Then, we represent the applications and technical challenges of OAM in communications, including free-space optical communications, optical fiber communications, radio communications and acoustic communications. To complete our survey, we also discuss the state of art of particle manipulation and target imaging with OAM beams.

“…Fig. 9.a∼c shows different OAMs vortex optical transmission and multiplexed optical field diagrams in simulation and experiments [37]. In this research, for information transmission, when using VM and VAM links that both adopt 8 OAM beams multiplexing, it was found that the BER of the received signal in VM links is lower, and with the increase of transmission power, these differences reveal an increasing trend as shown in Fig.…”

Optical vortex is a structured beam with a spiral phase wavefront. Different orbital angular momentums (OAM) are orthogonal to each other and multiplexed together without crosstalk. Vortex optical communication (VOC) can obtain good bandwidth and channel number. In this paper, we creatively exchanged the order of the spatial light modulator (SLM) and the optical switch, the communication link from "Vortex after Modulation (VAM)" to "Vortex Modulation (VM)", which constitutes a new link structure. Compared with the VAM communication link, the VM link has the advantages of higher transmission rate, better signal quality, lower signal error rate and so on. The results show that the VM link is 0.126 Gbit/s faster than the VAM on a single channel link, and 15.5 Gbit/s faster in 16-QAM 8 OAM beams multiplexing. The error rate of the received signal under the same conditions at the transmitting end has an improvement of 2∼4 orders of magnitude. The method is simple, convenient to implement, and has a significant improvement in transmission rate. It can provide a wide range of applications in vortex high-capacity communication.

“…[ 33 ] As an alternative, ideal single photon emitters or heralded photons can be used as the source requiring no change to the proof‐of‐principle demonstration outlined here. Further, while the distance in the laboratory was negligible, PVs have been collimated and sent over a free‐space communication link, [ 34 ] while their Fourier transformed state (Bessel beams) are likewise viable for long distance communication. [ 35,36 ] As such, real‐world deployment of our approach is feasible with appropriate engineering.…”

Quantum secret sharing is the art of securely sharing information between more than two people in such a way that its reconstruction requires the collaboration of a certain number of parties. Here, by taking advantage of the high‐dimensional Hilbert space for orbital angular momentum and using Perfect Vortex beams as their carriers, a proof‐of‐principle implementation of a high‐dimensional quantum secret sharing scheme is presented. This scheme is experimentally implemented with a fidelity of 93.4%, for 10 participants in d=11 dimensions—the highest number of participants and dimensions to date. The implementation can easily be scaled to higher dimensions and any number of participants, opening the way for securely distributing information across a network of nodes.
