Refractive index profile tailoring of multimode optical fibers for the spatial and spectral shaping of parametric sidebands
Katarzyna Krupa, Vincent Couderc, Alessandro Tonello +4
We introduce the concept of spatial and spectral control of nonlinear parametric sidebands in multimode optical fibers by tailoring their linear refractive index profile. In all ca…
Kerr beam self-cleaning on the mode in graded-index multimode fiber
E. Deliancourt, M. Fabert, A. Tonello +7
We report the experimental observation of Kerr beam self-cleaning in a graded-index multimode fiber, leading to output beam profiles different from a bell shape, close to the $LP_{…
Spatiotemporal light-beam compression from nonlinear mode coupling
Katarzyna Krupa, Alessandro Tonello, Vincent Couderc +4
We experimentally demonstrate simultaneous spatial and temporal compression in the propagation of light pulses in multimode nonlinear optical fibers. We reveal that the spatial bea…
Spatiotemporal Characterization of Supercontinuum Extending from the Visible to the Mid-Infrared in Multimode Graded-Index Optical Fiber
K. Krupa, C. Louot, V. Couderc +11
We experimentally demonstrate that pumping a graded-index multimode fiber with sub-ns pulses from a microchip Nd:YAG laser leads to spectrally flat supercontinuum generation with a…
Spatial beam self-cleaning in multimode fiber
Katarzyna Krupa, Alessandro Tonello, Badr M. Shalaby +5
Multimode optical fibres are enjoying a renewed attention, boosted by the urgent need to overcome the current capacity crunch of single-mode fibre systems and by recent advances in…
Efficiency of dispersive wave generation in dual concentric core microstructured fiber
Daniele Modotto, Marco Andreana, Katarzyna Krupa +10
We describe the generation of powerful dispersive waves that are observed when pumping a dual concentric core microstructured fiber by means of a sub-nanosecond laser emitting at t…
