Celebrating the 20^ th anniversary of Optics Express, this paper reviews the evolution of
optical fiber communication systems, and through a look at the previous 20 years attempts to …

Space-division multiplexing (SDM) uses multiplicity of space channels to increase capacity
for optical communication. It is applicable for optical communication in both free space and …

Multimode fibres (MMFs) are attracting interest in the study of spatiotemporal dynamics as
well as in the context of ultrafast fibre sources, imaging and telecommunications. This …

Mode-division multiplexing (MDM) using few-mode fibers (FMFs) appears as a promising
technology to increase fiber capacity by a few orders of magnitude and sustain the traffic …

In recent years, space-division multiplexed (SDM) transmission in multimode and multicore
fiber structures has been attracting growing interest as a mean of scaling the capacity of the …

Generally, light becomes scattered in space and time as it is coupled among multiple spatial
paths during propagation through disordered media or multimode waveguides. This limits …

Recent developments in spatially multiplexed optical communication systems demand a
deeper understanding of mode coupling effects in fibers. Spatial multiplexing is being …

In recent years, space-division multiplexing (SDM) has been proposed and investigated as a
technique to increase the per-fiber capacity in order to cope with the ever-increasing …

In this paper, we review linear propagation effects in a multimode fiber (MMF) and their
impact on performance and complexity in long-haul mode-division multiplexing (MDM) …

We derive the fundamental equations describing nonlinear propagation in multi-mode fibers
in the presence of random mode coupling within quasi-degenerate groups of modes. Our …
