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 ...

Observation of multimode solitons in few-mode fiber
Optics Letters, 2016 We experimentally isolate and directly observe multimode solitons in few-mode graded-index fiber. By varying the input energy and modal composition of the launched pulse, we observe a continuous variation of multimode solitons with different spatiotemporal properties. They exhibit an energy-volume relation that is distinct from those of single-mode and

Polarization-Maintaining Multi-Core Few-Mode Fiber With a Cladding Diameter of 125 μm
IEEE Photonics Journal, 2021 We present the theoretical study of polarization-maintaining multi-core few-mode fiber (PM MC-FMF) with a cladding diameter of 125 μm, in order to secure the maximum number of independent spatial channels arising in the single fiber.

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 ...

Phase-Sensitive Mode Conversion and Equalization in a Few Mode Fiber Through Parametric Interactions
IEEE Photonics Journal, 2017 The parametric interaction in few mode fibers is theoretically and numerically studied in the particular case in which the signal and the idler waves are frequency degenerate but mode nondegenerate.

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.

Design of Highly Elliptical Core Ten-Mode Fiber for Space Division Multiplexing With 2 × 2 MIMO
IEEE Photonics Journal, 2019 In this paper, we propose a weakly coupled few-mode fiber requiring only 2 × 2 multi-in multi-out equalizer blocks, which makes it compatible with standard coherent receivers with polarization diversity.

Deep Learning for Computational Mode Decomposition in Optical Fibers
Applied Sciences, 2020 Multimode fibers are regarded as the key technology for the steady increase in data rates in optical communication. However, light propagation in multimode fibers is complex and can lead to distortions in the transmission of information.
