Few-Mode Fibers: Characterizations and Applications
2023 Optical Fiber Communications Conference and Exhibition (OFC), 2023 We report design guidelines and modal loss characterizations (light scattering and extra-loss phenomena) of few-mode fibers that allow optimizing their crosstalk, differential mode group delay and differential mode attenuation for practical applications.

Fast mode decomposition in few-mode fibers [PDF]
Nature Communications, 2020 AbstractRetrieval of the optical phase information from measurement of intensity is of a high interest because this would facilitate simple and cost-efficient techniques and devices. In scientific and industrial applications that exploit multi-mode fibers, a prior knowledge of spatial mode structure of the fiber, in principle, makes it possible to ...

M2 factor for evaluating fiber lasers from large mode area few-mode fibers
Frontiers in Physics, 2023 Evaluating the laser quality accurately is one of the most important and fundamental physical issues for laser sources, and the beam quality of lasers from the large mode area few-mode fibers have been haunted by the presence of high order mode for many ...

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 ...

Selective wavelength conversion in a few-mode fiber [PDF]
Optics Express, 2019 We experimentally demonstrate a means to selectively enhance wavelength conversion of WDM channels on a 100 GHz grid exploiting nonlinear effects between the spatial modes of a few mode fiber. The selectivity of parametric gain is obtained by dispersion design of the fiber such that the inverse group velocity curves of the participating modes are ...

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.
