Fast mode decomposition in few-mode fibers [PDF]
Nature Communications, 2020 Characterizing the modes at the output of a multimode fiber is time consuming due to computational cost. Here the authors present an algorithm for few-mode-fiber mode decomposition with a fast processing time and using only intensity measurements.

Forward Brillouin scattering in few-mode fibers [PDF]
Light: Science & ApplicationsForward Brillouin scattering is an opto-mechanical effect in which two co-propagating optical fields couple with an acoustic mode in a common medium. The effect has been studied in standard optical fibers since 1985, however nearly all studies have been ...

Intrinsic loss of few-mode fibers
Optics Express, 2018 We summarize theoretical formulae for determining the intrinsic loss of few-mode fibers and compare intrinsic losses among step-index and parabolic graded-index few-mode fibers (FMF) with different dopants, and with single-mode fibers (SMF). The low-loss characteristics of pure-silica-core FMFs, in comparison with SMFs, give rise to additional ...

Long distance transmission in few-mode fibers
Optics Express, 2010 Using multimode fibers for long-haul transmission is proposed and demonstrated experimentally. In particular few-mode fibers (FMFs) are demonstrated as a good compromise since they are sufficiently resistant to mode coupling compared to standard multimode fibers but they still can have large core diameters compared to single-mode fibers.

Rayleigh scattering in few-mode optical fibers [PDF]
Scientific Reports, 2016 AbstractThe extremely low loss of silica fibers has enabled the telecommunication revolution, but single-mode fiber-optic communication systems have been driven to their capacity limits. As a means to overcome this capacity crunch, space-division multiplexing (SDM) using few-mode fibers (FMF) has been proposed and demonstrated.

Towards universal multi-dimensional parallelization communications by direct diverse fiber/3D/2D chip hybrid integration [PDF]
Nature CommunicationsSpace-division multiplexing (SDM) is a promising technology for significantly increasing the capacity of a single fiber or waveguide. Various SDM fibers, including few-mode fibers (FMFs), multi-core fibers (MCFs), and orbital angular momentum fibers ...

Wideband and Low-Loss Mode Scrambler for Few-Mode Fibers Based on Distributed Multiple Point-Loads
IEEE Photonics Journal, 2021 We propose a new type of all-fiber mode scrambler for mode division multiplexed data transmission based on few mode fibers. By randomly placing multiple point-loads along the fiber length, low loss and wideband mode coupling is obtained amongst all the ...

Journal of Lightwave Technology, 2018 Few-mode lensed fiber for focusing multiple spatial modes with minimal distortion are proposed and investigated numerically and experimentally, for the first time to the best of the authors’ knowledge. Although the conventional hyperbolic lens profile works effectively for the fundamental mode, it introduces severe distortion for high-order radial ...
