Paper Abstract

Optical communications has historically experienced capacity growth by multiplexing many channels, and space-division-multiplexing (SDM) appears to be the next domain to exploit. SDM can encompass multiple spatially overlapping “orthogonal” modes to achieve mode-division-multiplexing (MDM). Key advantages of modal orthogonality are the ability to efficiently (de)multiplex independent data streams and co-propagate them, all with little inherent crosstalk. An MDM approach using orbital angular momentum (OAM) has emerged as a potential method to efficiently multiplex many spatially over-lapping data-carrying beams. This presentation will highlight transmission of multiple OAM beams as well as the various technical challenges in realizing such a system.
