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…
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…
Nonlinear polarization dynamics of Kerr beam self-cleaning in a GRIN multimode optical fiber
Katarzyna Krupa, Graciela Garmendia Castañeda, Alessandro Tonello +8
We experimentally study polarization dynamics of Kerr beam self-cleaning in a graded-index multimode optical fiber. We show that spatial beam cleaning is accompanied by nonlinear p…
Kerr beam self-cleaning in the multimode fiber anomalous dispersion regime
Y. Leventoux, A. Parriaux, O. Sidelnikov +13
We experimentally demonstrate Kerr beam self-cleaning in the anomalous dispersion regime of graded-index multimode optical fibers. By using 90 ps duration, highly chirped (2 nm ban…
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_{…
Nonlinear dynamics in multimode optical fibers
Stefan Wabnitz, Alessandro Tonello, Vincent Couderc +4
We overview recent advances in the research on spatiotemporal beam shaping in nonlinear multimode optical fibers. An intense light beam coupled to a graded index (GRIN) highly mult…
Interplay of Kerr and Raman beam cleaning with a multimode microstructure fiber
R. Dupiol, K. Krupa, A. Tonello +5
We experimentally study the competition between Kerr beam self-cleaning and Raman beam cleanup in a multimode air-silica microstructure optical fiber. Kerr beam self-cleaning of th…
Seeded intermodal four-wave mixing in a highly multimode fiber
A. Bendahmane, K. Krupa, A. Tonello +5
We experimentally and theoretically investigate the process of seeded intermodal four-wave mixing in a graded index multimode fiber, pumped in the normal dispersion regime. By usin…
