High-Capacity Optical and RF Communications using Multiplexing of Multiple Orbital-Angular-Momentum Beams

The ability to multiplex multiple, spatially overlapping data-carrying modes over the same physical medium represents the potential for increasing system capacity and spectral efficiency. Generating different amounts of orbital-angular-momentum (OAM) on different optical beams has emerged as a technique for such mode multiplexing.  Each OAM beam is orthogonal and can be efficiently multiplexed and demultiplexed, and OAM is compatible with other forms of multiplexing (e.g., polarization multiplexing and WDM). This presentation will explore the achievements of and challenges to OAM-based optical and RF communication systems, including transmission and switching.
