Giving light a new twist with standard optical fibres: rainbow Archimedean spiral emission
F. Mangini, M. Ferraro, M. Zitelli +8
We demonstrate a new practical approach for generating multicolour spiral-shaped beams. It makes use of a standard silica optical fibre, combined with a titled input laser beam. Th…
Collapse events of two-color optical beams
Alexey Sukhinin, Alejandro B Aceves, Jean-Claude Diels +1
In this work, we study optical self-focusing that leads to collapse events for the time-independent model of co-propagating beams with different wavelengths. We show that collapse…
Light dynamics in nonlinear trimers and twisted multicore fibers
Claudia Castro-Castro, Yannan Shen, Gowri Srinivasan +2
Novel photonic structures such as multi-core fibers and graphene based arrays present unique opportunities to manipulate and control the propagation of light. Here we discuss nonli…
Existence, Stability and Dynamics of Discrete Solitary Waves in a Binary Waveguide Array
Y. Shen, P. G. Kevrekidis, G. Srinivasan +1
Recent work has explored binary waveguide arrays in the long-wavelength, near-continuum limit, here we examine the opposite limit, namely the vicinity of the so-called anti-continu…
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…
