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 …

Single-mode fiber's physical capacity boundaries will soon be reached; hence, alternative
solutions are much needed to overcome the multiplying and remarkably large bandwidth …

Space-division multiplexing (SDM) is an attractive technique for dramatically enhancing the
transmission capacity in a single optical fiber. Recently, ultradense SDM transmission …

Multicore fibers (MCFs) are expected as a good candidate for overcoming the capacity limit
of a current optical communication system. This paper describes the recent progress on the …

Space-division multiplexing (SDM) technology is a promising candidate to achieve massive
parallelism in optical fiber cables and overcome the capacity limitation of the conventional …

In this paper, we describe recent progress in space-division multiplexed (SDM)
transmission, and our proposal and demonstration of dense space-division multiplexing …

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

We show the design and applicability of multi-core fiber (MCF) with the standard 125 μm
cladding diameter to the telecommunication systems. It offers easier and practical use of the …

We report the optimization of a few-mode fiber, adapted to multiple-input multiple-output
mode division multiplexing, that supports 9 LP modes (15 spatial modes). The fiber is …

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 …
