Block-Based Mode Decomposition in Few-Mode Fibers
PhotonicsA 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 ...

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 ...

Transverse Asymmetry of the Index Modulation Profile in Few-Mode Fiber Bragg Grating
Photonics, 2021 The transverse asymmetry of the index modulation profile in the asymmetric few-mode fiber Bragg grating (FM-FBG) was investigated. The transverse asymmetry of the index modulation profile will lead to mode conversion between modes with the different ...

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-Fiber Technology Fine-tunes Losses in Quantum Communication Systems [PDF]
Physical Review Applied, 2021 A natural choice for quantum communication is to use the relative phase between two paths of a single-photon for information encoding. This method was nevertheless quickly identified as impractical over long distances and thus a modification based on ...

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.

A Comparative Study of Few-Mode Fiber and Coupled-Core Multi-Core Fiber Transmission
Journal of Lightwave Technology, 2022 Few-mode fibers and coupled-core multi-core fibers are attractive transmission media for space-division multiplexed transmission systems as they enable a high spatial channel multiplicity whilst sustaining the current standard cladding diameter.
