Optical Poling Reveals Hidden Molecular Restructuring in Multimode Fibers, Unlocking Ultra-Efficient Third-Order Nonlinearities
Maxime Jonard, Thomas Larqué, Dan-Esli Bouyou Bouyou +10
Optical poling is a well-established technique for inducing χ^{(2)} nonlinearity, yet its impact on silica's molecular structure remains unexplored. Here, we report the first direc…
Frequency-Resolved Spatial Beam Mapping in Multimode Fibers: Application to Mid-Infrared Supercontinuum Generation
Y. Leventoux, G. Granger, K. Krupa +6
We present a new spatial-spectral mapping technique permitting to measure the beam intensity at the output of a graded-index (GRIN) multimode fiber with sub-nanometric spectral res…
Spatiotemporal beam self-cleaning for high-resolution nonlinear fluorescence imaging with multimode fibres
Nawell Ould Moussa, Tigran Mansuryan, Charles Henri Hage +12
Beam self-cleaning (BSC) in graded-index (GRIN) multimode fibres (MMFs) has been recently reported by different research groups. Driven by the interplay between Kerr effect and bea…
Coherent combining of self-cleaned multimode beams
Marc Fabert, Maria Săpânţan, Katarzyna Krupa +9
A low intensity light beam emerges from a graded-index, highly multimode optical fibre with a speckled shape, while at higher intensity the Kerr nonlinearity may induce a spontaneo…
Spatial beam self-cleaning in tapered Yb-doped GRIN multimode fiber with decelerating nonlinearity
A. Niang, D. Modotto, A. Tonello +12
We experimentally demonstrate spatial beam self-cleaning in an Yb-doped graded-index multimode fiber taper, both in passive and active configurations. The input laser beam at 1064…
Spatial beam self-cleaning in multimode lanthanum aluminum silicate glass fiber
Romain Guénard, Katarzyna Krupa, Alessandro Tonello +11
We demonstrated that spatial Kerr beam self-cleaning can be obtained in a highly multimode multicomponent optical fiber based on lanthanum aluminum silicate oxide glasses (SiO2-Al2…
