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

open access: yes, 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

Statistical Analysis of Differential Group Delay in Few-Mode Spun Optical Fiber [PDF]

open access: yes, 2022
This thesis proposes a statistical analysis of the differential group delay in few-mode optical fibers. The numerical analysis is performed by an accurate modeling of the propagation and coupling of a few-mode fiber, supporting the first 4 LP groups ...

Intrinsic loss of few-mode fibers

open access: yesOptics 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 ...

Overcoming the OTDR dead-zone using a few-mode fiber

open access: yes, 2021
Optical-time-domain-reflectometer (OTDR) suffers from the existence of dead-zones along a deployed fiber under test (FUT). Within a dead-zone, OTDR typically fails to provide any reliable diagnostic information.

Polarization-Maintaining Multi-Core Few-Mode Fiber With a Cladding Diameter of 125 μm

open access: yesIEEE 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

open access: yes, 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
