In optical communications, space-division multiplexing is a promising strategy to augment the fiber network capacity. It relies on modern fiber designs that support the propagation of multiple spatial modes. One of these fibers, the ring-core fiber (RCF), is able to propagate modes that carry orbital angular momentum (OAM), and has been shown to enhance not only classical, but also quantum communication systems. Typically, the RCF spatial modes are used as orthogonal transmission channels for… Expand

Terabit-Scale Orbital Angular Momentum Mode Division Multiplexing in Fibers
TLDR
The viability of using the orbital angular momentum (OAM) of light to create orthogonal, spatially distinct streams of data-transmitting channels that are multiplexed in a single fiber is demonstrated and suggest that OAM could provide an additional degree of freedom for data multiplexing in future fiber networks.

Capacity Limits of Optical Fiber Networks
We describe a method to estimate the capacity limit of fiber-optic communication systems (or ΒΏfiber channelsΒΏ) based on information theory. This paper is divided into two parts. Part 1 reviews… Expand

TLDR
This work designs and fabricates a graded-index ring-core fiber to effectively suppress radially high-order modes and greatly separate high- order OAM mode groups, and experimentally demonstrates 8.4Β Tbit/s data transmission in an 18Β km OAM fiber with low crosstalk. Expand

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 low-crosstalk ring-core… Expand
Scalable mode division multiplexed transmission over a 10-km ring-core fiber using high-order orbital angular momentum modes.
TLDR
Given the fixed number of modes in each mode group and the low inter-mode-group coupling in ring core fibres, this scheme has good potential for capacity upscaling at an expense of only modularly increasing the number of mode-groups with fixed-size (4x4) MIMO blocks. Expand
