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…
Raman-Accelerated Power Depletion of Fundamental Mode in a Few-Mode Fiber in the Visible Spectral Range
Wasyhun A. Gemechu, Guohao Fu, Mario Zitelli
We experimentally and numerically investigate Raman-driven power depletion in the fundamental mode of few-mode fibers (FMFs) excited by visible ultrashort pulses. Using a tunable f…
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…
