Generation of High-order Laguerre-Gaussian modes in Coated and Uncoated Graded-Index and Step-Index Multimode Fibers
Wasyhun Asefa Gemechu, Umberto Minoni, Michela Borghetti +4
We report an efficient experimental method for generating high-order Laguerre-Gauss (HOLG) modes by simply coupling a Gaussian beam into the cladding of a multimode fiber (MMF). In…
Extreme nonlinear optics in optical fibers
Mario Ferraro, Bertrand Kibler, Pierre Béjot +5
This paper reviews the field of extreme nonlinear optics in optical fibers, highlighting key phenomena and advancements. It discusses multiple ionization effects caused by femtosec…
Multiscale X-ray computed tomography of standard optical fibers
Maria Caterina Crocco, Flavio Cognigni, Alessia Sanna +12
Optical fiber technologies enable high-speed communication, medical imaging, and advanced sensing. Among the techniques for the characterization of optical fibers, Xray computed to…
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…
Modal division multiplexing of quantum and classical signals in few-mode fibers
Danilo Zia, Mario Zitelli, Gonzalo Carvacho +3
Mode-division multiplexing using multimode optical fibers has been intensively studied in recent years, in order to alleviate the transmission capacity crunch. Moreover, the need f…
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…
