Mode-division multiplexing over fibers has attracted increasing attention over the last few
years as a potential solution to further increase fiber transmission capacity. In this paper, we …

Twisted light carrying orbital angular momentum (OAM) is a special kind of structured light
that has a helical phase front, a phase singularity, and a doughnut intensity profile. Beyond …

We experimentally demonstrate mode-division multiplexed (MDM) transmission using eight
orbital angular momentum (OAM) modes over a single span of 100-km low-attenuation and …

Simultaneous MIMO-free transmission of 12 orbital angular momentum (OAM) modes over a
1.2 km air-core fiber is demonstrated. WDM compatibility of the system is shown by using 60 …

Mode-division multiplexing (MDM), which employs the spatial modes of light as information
carriers, has been widely investigated to increase the transmission capacity. Few-mode …

The quickly increasing data transfer load requires an urgent revolution in current optical
communication. Orbital angular momentum (OAM) multiplexing is a potential candidate with …

We demonstrate the first MDM scheme using OAM states over 1.1-km of fiber. This is
enabled by a SLM-based Mux/Demux setup, and a fiber designed to propagate multiple …

Mode division multiplexing (MDM) systems using orbital angular momentum (OAM) modes
can recover the data in D different modes without recourse to full (2D× 2D) multiple input …

Orbital angular momentum (OAM) modes, having unique properties of a helical phase
structure and doughnut intensity profile, have been widely studied in fiber-optic …

Mode-division multiplexing passive optical network (MDM-PON) is a promising scheme for
next-generation access networks to further increase fiber transmission capacity. In this …
