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…

Spatio-spectral light-by-light moulding in multimode fibre

Yago Arosa, Tigran Mansuryan, Arnaud Poisson +8

Controlling complex light waves to achieve desired behaviours or characteristics on demand presents a significant challenge. This task becomes even more complicated when manipulati…

Concatenation of Kerr solitary waves in Ceramic YAG: application to coherent Raman imaging

Nicholas Bagley, Sahar Wehbi, Tigran Mansuryan +12

A coherent concatenation of multiple Townes solitons may lead to a stable infrared and visible broadband filament in ceramic YAG polycrystal. This self-trapped soliton train is lev…

Light tailored by multimode fiber for multiphoton fluorescence microscopy

Raphael Jauberteau, Alessandro Tonello, Yifan Sun +8

We study the diffraction of a particular class of beams, composed only by a combination of azimuthally invariant guided modes of an optical fiber. We demonstrate that such beams ca…

Exploitation of the nonresonant background of Multiplex-Coherent anti-Stokes Raman Scattering for label-free discrimination of proteins

Malik Nafa, Tigran Mansuryan, Vincent Couderc +9

We propose a novel approach using Multiplex-Coherent Anti-Stokes Raman Scattering (M-CARS) for la-bel-free discriminations in biomedical tissues. The strategy is based on the evalu…

Spatial Division Multiplexing for Multiplex Coherent Anti-Stokes Raman Scattering

T. Mansuryan, A. Tonello, K. Krupa +12

We demonstrate how a narrowband pump and a broadband spectrum can be spatially multiplexed by selective coupling them in two distinct modes of a few-mode microstructure fiber. The…

Numerical analysis of beam self-cleaning in multimode fiber amplifiers

Mesay Addisu Jima, Alessandro Tonello, Alioune Niang +6

Recent experimental results have reported the observation of beam self-cleaning or, more generally, nonlinear beam reshaping in active multimode fibers. In this work we present a n…

Twin Spotlight Beam Generation in Quadratic Crystals

Raphaël Jauberteau, Sahar Wehbi, Tigran Mansuryan +6

Optical rogue waves have been extensively studied in the past two decades. However, observations of multidimensional extreme wave events remain surprisingly scarce. In this work we…

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…
