Multi-element fiber for space-division multiplexed optical communication system [PDF]

, 2014
This paper reviews a novel approach of implementing space-division multiplexing (SDM) based on Multi-element Fiber (MEF) technology. The MEF geometry provides for ultra-low crosstalk between the spatial channels while full compatibility with standard WDM

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.

Few-Mode Fiber Coupling Efficiency for Free-Space Optical Communication

, 2020
Few-mode fiber is a significant component of free-space optical communication at the receiver to obtain achievable high coupling efficiency. A theoretical coupling model from the free-space optical communication link to a few-mode fiber is proposed based

Octave spanning supercontinuum generation with a few-mode fiber [PDF]

, 2020
We propose and demonstrate the generation of a supercontinuum with a few-mode fiber. Due to the accommodation of a few-mode fiber in LP01 and LP11 modes, the system was engineered to detect the octave spanning supercontinuum in both modes.

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

Intensity-only-measurement mode decomposition in few-mode fibers [PDF]

Optics Express, 2021
Recovery of optical phases using direct intensity detection methods is an ill-posed problem and some prior information is required to regularize it. In the case of multi-mode fibers, the known structure of eigenmodes is used to recover optical field and find mode decomposition by measuring intensity distribution.

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.

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.
