Random Mode Coupling Assists Kerr Beam Self-Cleaning in a Graded-Index Multimode Optical Fiber
Oleg S. Sidelnikov, Evgeniy V. Podivilov, Mikhail P. Fedoruk +1
In this paper, we numerically investigate the process of beam self-cleaning in a graded-index multimode optical fiber, by using the coupled-mode model. We introduce various models…

Hydrodynamic 2D turbulence and spatial beam condensation in multimode optical fibers
E. V. Podivilov, D. S. Kharenko, V. A. Gonta +6
We show that Kerr beam self-cleaning results from parametric mode mixing instabilities, that generate a number of nonlinearly interacting modes with randomized phases -- optical wa…
