Spatio-temporal beam dynamics in multimode nonlinear optical fibers [PDF]
, 2017 We overview recent advances in the spatio-temporal nonlinear dynamics of optical pulses propagating in multimode optical fibers. The Kerr effect leads to spatial beam self-cleaning in a graded-index multimode optical fiber, followed by sideband series ...

Fast and accurate modelling of nonlinear pulse propagation in graded-index multimode fibers [PDF]
, 2017 We develop a model for the description of nonlinear pulse propagation in multimode optical fibers with a parabolic refractive index profile. It consists in a 1+1D generalized nonlinear Schr\"odinger equation with a periodic nonlinear coefficient, which ...
