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 …

Optical communication technology has been advancing rapidly for several decades,
supporting our increasingly information-driven society and economy. Much of this progress …

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 …

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 …

We investigate theoretically nonlinear transmission in space-division multiplexed (SDM)
systems using multimode fibers exhibiting rapidly varying birefringence. A primary objective …

We describe the design trade-offs that are at stake when optimizing few-mode fibers (FMFs)
that support a high number (6) of LP modes. We particularly detail the design of 6-LP-mode …

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 …

Transmission of a 73.7 Tb/s (96x3x256-Gb/s) DP-16QAM mode-division-multiplexed signal
over 119km of few-mode fiber transmission line incorporating an inline multi mode EDFA …

Optical fibers have often been considered to offer effectively infinite capacity to support the
rapid traffic growth essential to our information society. However, as demand has grown and …

We simulate and analyze the mode properties and propagation effects of orbital angular
momentum (OAM) modes in a ring fiber. A ring fiber with 0.05 up-doping is designed in …
