Block-Based Mode Decomposition in Few-Mode Fibers

Photonics
A block-based mode decomposition (BMD) algorithm is proposed in this paper, which reduces computational complexity and enhances noise resistance. The BMD uses randomly selected sample blocks of the beam images to restore mode coefficients instead of all ...

Multi-element fiber for space-division multiplexing

, 2013
A novel approach of using multi-element fiber (MEF) technology in space-division multiplexing (SDM) systems is presented. This paper reviews the progress in fabrication and characterization of MEF based both ultra-low crosstalk transmission and amplifier

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.

Accurate Analysis of Crosstalk Between LP$_{11}$ Quasi-Degenerate Modes Due to Offset Connection Using True Eigenmodes

IEEE Photonics Journal, 2018
Linearly polarized (LP) modes in few-mode fibers are not true eigenmodes but approximated modes constituting of linear combinations of true eigenmodes.

Linking neurogenesis, oligodendrogenesis, and myelination defects to neurodevelopmental disruption in primary mitochondrial disorders

FEBS Letters, EarlyView.
Mitochondrial remodeling shapes neural and glial lineage progression by matching metabolic supply with demand. Elevated OXPHOS supports differentiation and myelin formation, while myelin compaction lowers mitochondrial dependence, revealing mitochondria as key drivers of developmental energy adaptation.

Dead Zone Fault Detection Optimization Method for Few-Mode Fiber Links Based on Unexcited Coupled Higher-Order Modes

Photonics
The traditional single-mode fiber (SMF) optical time domain reflectometer (OTDR) may not be able to accurately detect and locate fault events in the dead zone of few-mode fiber (FMF) links.

Dynamic Control of Distal Spatial Mode Pattern Output From Multimode Fiber Using Integrated Coherent Network

IEEE Photonics Journal, 2023
The mode field distribution at the distal end of a multimode fiber can vary randomly when environmental perturbations introduce changes in the relative phases of different eigenmodes and variations in coupling among modes.

Mode-resolved nonlinear absorption characteristics of few-mode fiber-multimode fiber-few-mode fiber structures

Optics Express
We report a systematic investigation on the mode-resolved nonlinear absorption characteristics of the few-mode fiber-multimode fiber-few-mode fiber (FMF) structure. Firstly, the transmission formulas of the FMF structure are derived, demonstrating that the transmission is mode-dependent.

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

FEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.
