Low-DMD and low-crosstalk few-mode multi-core fiber with air-trench/holes assisted graded-index profile
TL;DR: In this article, an air-trench/hole assisted (AT-AH) heterogeneous few-mode multi-core fiber (hetero-FM-MCF) with high density of cores and low inter-core crosstalk (XT) was proposed.

Impact analysis of a dense hole-assisted structure on crosstalk and bending loss in homogeneous few-mode multi-core fibers.
TL;DR: Through numerical simulations, it is shown that the DHAS has great contribution to meet the XT value requirement of lower than -30 dB/100km and make the bending loss values satisfy the ITU-T recommendations of G. 654 in a 7-core 4-LP-mode fiber with a 125-μm cladding diameter.

Design and Characterization of Nanopore- Assisted Weakly-Coupled Few-Mode Fiber for Simpler MIMO Space Division Multiplexing
TL;DR: A novel weakly-coupled 6-LP-mode fiber that features a nanopore-assisted step-index core with double-cladding profile to alleviate modes coupling and bend sensitivity, thus simplifies the multiple-input multiple-output (MIMO) process and the environmental requirements in which the fiber is used.

A Weakly-Coupled Few-Mode Optical Fiber With a Graded Concave High-Index-Ring
TL;DR: In this article, the authors proposed a novel refractive index profile design based on few-mode fibers (FMFs) which can support 4 linear polarization (LP) modes, and they first presented a FMF whose core is dually assisted by a nano-hole (NH) and a high index-ring (HIR), and then substitute the dual assistance by an innovative graded concave HIR (GC-HIR) assisted structure.
