Self-Focusing in Multicore Fibers
Advanced Solid State Lasers, 2014 Self-focusing is the ultimate power limit of single mode fiber amplifiers. As fiber technology is approaching this limit, ways to mitigate self-focusing are becoming more and more important. Here we show a theoretical analysis of this limitation in coupled multicore fibers.

Writing Bragg Gratings in Multicore Fibers [PDF]
Journal of Visualized Experiments, 2016 Fiber Bragg gratings in multicore fibers can be used as compact and robust filters in astronomical and other research and commercial applications. Strong suppression at a single wavelength requires that all cores have matching transmission profiles. These gratings cannot be inscribed using the same method as for single-core fibers because the curved ...

Optimal crosstalk suppression in multicore fibers [PDF]
Scientific Reports, 2019 AbstractWe study propagation in a cyclic symmetric multicore fiber where the core radii randomly fluctuate along the propagation direction. We propose a hybrid analytic-numerical method to optimize the amplitude and frequency of the fluctuations that suppress power transfer between outer and inner cores.

Single-shot non-interferometric measurement of the phase transmission matrix in multicore fibers [PDF]
, 2018 A simple technique for far-field single-shot non-interferometric determination of the phase transmission matrix of a multicore fiber with over 100 cores is presented. This phase retrieval technique relies on the aperiodic arrangement of the cores.Comment:

Random raman fiber laser based on a twin-core fiber with FBGs inscribed by femtosecond radiation [PDF]
, 2019 Narrowband Raman lasing in a polarization-maintaining two-core fiber (TCF) is demonstrated. Femtosecond point-by-point inscription of fiber Bragg gratings (FBGs) in individual cores produces a half-open cavity with random distributed feedback.
