In order to overcome the capacity limitations of current lightwave systems based on the
single-mode optical fiber, massively parallel transmission in the spatial domain [space …

Research on space-division multiplexing (SDM) came to prominence in early 2010 being
primarily proposed as a means of multiplying the information-carrying capacity of optical …

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 …

Four-mode multiplexing and manipulation technologies are reviewed in the context of space-
division multiplexing (SDM) optical communication systems. These are multiplane light …

The potential transmission capacity of a standard single-mode fiber peaks at around
100Tb/s owing to fiber nonlinearity and the bandwidth limitation of amplifiers. As the last …

We propose and demonstrate a scalable mode division multiplexing scheme based on
orbital angular momentum modes in ring core fibers. In this scheme, the high-order mode …

Multicore fibers and few-mode fibers have potential application in realizing dense-space-
division multiplexing systems. However, there are some tradeoff requirements for designing …

In this paper, we review recent progress on space division multiplexed (SDM) transmission
and our proposal of dense SDM (DSDM) with more than 30 spatial channels toward …

In this paper, we review space division multiplexing (SDM) transmission experimental
demonstrations and associated technologies. In past years, SDM achieved high capacity …

50-μm-diameter graded-index core multimode fibers can be adapted to mode-division-
multiplexed transmissions that use multiple-input-multiple-output digital signal processing …
