Abstract

There has been extensive interest in increasing data capacity and spectral efficiency of free-space optical (FSO) communications. This chapter reviews the principle and experimental demonstrations of utilizing the orbital angular momentum (OAM) multiplexing to achieve high-capacity FSO systems. Topics in this chapter include technical challenges, first-of-its-kind demonstrations of OAM-multiplexed FSO links, mitigation approaches for inter-channel crosstalk, and OAM systems in airborne and underwater environments. Potential further investigation and exploration of OAM multiplexing techniques are also discussed in each section of this chapter.
