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…
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…
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…
Efficiency of dispersive wave generation in dual concentric core microstructured fiber
Daniele Modotto, Marco Andreana, Katarzyna Krupa +10
We describe the generation of powerful dispersive waves that are observed when pumping a dual concentric core microstructured fiber by means of a sub-nanosecond laser emitting at t…
Dispersive wave emission in dual concentric core fiber: the role of soliton-soliton collisions
Alessandro Tonello, Daniele Modotto, Katarzyna Krupa +7
Soliton-soliton collisions have a crucial role in enhancing the spectrum of dispersive waves in optical fibers and collisions among in-phase solitons lead to a dramatic enhancement…
