Space-time excitation creates soliton trains in multimode fibers
Julien Dechanxhe, Spencer W. Jolly, Pascal Kockaert
In this work, we show that injecting a single space-time-coupled light pulse-beam into a multimode graded-index fiber generates a train of multimode solitons. Space-time couplings…

Accessing different higher-order modes with nonlinear modal energy transfer under simple realistic tuning of initial conditions
Julien Dechanxhe, Pascal Kockaert, Spencer W. Jolly
The initial conditions in multi-mode fibers pumped by ultrashort laser pulses strongly determine the following nonlinear optical interactions. In this work we firstly compare the d…

Propagation of space-time optical vortices in multimode fibers
Spencer W. Jolly, Julien Dechanxhe, Pascal Kockaert
The non-intuitive spatiotemporal modal content of space-time optical vortices (STOVs) is calculated in a graded-index fiber supporting a large number of propagating modes. We discu…
