Few-mode fiber based optical sensors

Optics Express, 2015
Few-mode fibers (FMFs) have found applications in optical communications and sensors with attractive features that standard single mode fiber (SSMF) do not possess. We report our recent progress on FMF based optical sensors, and show the potential of utilizing the spatial dimension for multi-parameter sensing with discrimination capability.

Learning the matrix of few-mode fibers for high-fidelity spatial mode transmission

APL Photonics, 2022
Few-mode fibers (FMFs) are promising for advancements in transmission capacity in classical and quantum communications. However, the inherent modal crosstalk limits the practical application of FMF.

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.

Few-Mode Lensed Fibers

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 ...

Nonlinear Pulse Distortion in Few-Mode Fiber [PDF]

European Conference and Exhibition on Optical Communication, 2012
Nonlinear pulse propagation in a few mode fiber is experimentally investigated, by measuring temporal and phase responses of the output pulses by use of a frequency discriminator technique, showing that self-phase modulation, dispersion and linear mode-coupling are the dominant effects.

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 ...
