Fiber Residual Stress Effects on Modal Gain Equalization of Few-Mode Fiber Amplifier [PDF]

Sensors, 2023
The modal gain equalization (MGE) of few-mode fiber amplifiers (FMFAs) ensures the stability of signal transmission. MGE mainly relies on the multi-step refractive index (RI) and doping profile of few-mode erbium-doped fibers (FM-EDFs).

Transverse mode coupling in monolithic few-mode fiber laser oscillators [PDF]

Light: Science & Applications
Transverse mode instability (TMI), induced by nonlinear thermal-optical coupling, poses a primary challenge for the power scaling of fiber lasers. In the fiber oscillator, a sealed resonant cavity, TMI could become particularly complex due to the mode ...

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.

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 ...

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 ...

High-Order Mode Mode-Locked Fiber Laser Based on Few-Mode Saturable Absorber

IEEE Photonics Journal, 2021
We presented two kinds of high-order mode (HOM) mode-locked fiber lasers based on few-mode (FM) saturable absorbers for direct HOM oscillation. One is a ring fiber laser based on a carbon nanotube (CNT) saturable absorber (SA), in which the combination ...

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.
