Performance Metrics and Design Parameters for a Free-space Communication Link Based on Multiplexing of Multiple Orbital-Angular-Momentum Beams
We study the design parameters for an orbital angular momentum (OAM) multiplexed free-space data link. Power loss, channel crosstalk and power penalty of the link are analyzed in the case of misalignment between the transmitter and receiver (lateral displacement, receiver angular error, or transmitter pointing error). The relationship among the system power loss and link distance, transmitted b...
متن کاملOrbital-angular-momentum-multiplexed free-space optical communication link using transmitter lenses.
In this paper, we explore the potential benefits and limitations of using transmitter lenses in an orbital-angular-momentum (OAM)-multiplexed free-space optical (FSO) communication link. Both simulation and experimental results indicate that within certain transmission distances, using lenses at the transmitter to focus OAM beams could reduce power loss in OAM-based FSO links and that this impr...
متن کاملCapacity limits of spatially multiplexed free-space communication
Increasing the information capacity per unit bandwidth has been a perennial goal of scientists and engineers1. Multiplexing of independent degrees of freedom, such as wavelength, polarization and more recently space, has been a preferred method to increase capacity2,3 in both radiofrequency and optical communication. Orbital angular momentum, a physical property of electromagnetic waves discove...
متن کاملExperimental characterization of a 400 Gbit/s orbital angular momentum multiplexed free-space optical link over 120 m.
We experimentally demonstrate and characterize the performance of a 400-Gbit/s orbital angular momentum (OAM) multiplexed free-space optical link over 120 m on the roof of a building. Four OAM beams, each carrying a 100-Gbit/s quadrature-phase-shift-keyed channel are multiplexed and transmitted. We investigate the influence of channel impairments on the received power, intermodal crosstalk amon...
متن کاملFree-Space Coherent Optical Communication Demonstration using a 3D Photonic Integrated Circuit Device for Orbital Angular Momentum Multiplexing/Demultiplexing
We show error-free 10 GBd QPSK data transmission performance using orbital angular momentum (OAM) modes that are multiplexed and demultiplexed by a low-loss, hybrid-integrated device based on a silica planar lightwave circuit (PLC) coupled to a 3-D photonic integrated circuit.
