Stable bright and vortex solitons in photonic crystal fibers with inhomogeneous defocusing nonlinearity
Valery E. Lobanov, Olga V. Borovkova, Yaroslav V. Kartashov +2
We predict that a photonic crystal fiber whose strands are filled with a defocusing nonlinear medium can support stable bright and also vortex solitons if the strength of the defoc…
Vortex soliton tori with multiple nested phase singularities in dissipative media
Olga V. Borovkova, Valery E. Lobanov, Yaroslav V. Kartashov +1
We show the existence of stable two- and three-dimensional vortex solitons carrying multiple, spatially separated, single-charge topological dislocations nested around a vortex-rin…
Topological light bullets supported by spatio-temporal gain
Valery E. Lobanov, Olga. V. Borovkova, Yaroslav V. Kartashov +2
We reveal that the competition between diffraction, cubic nonlinearity, two-photon absorption, and gain localized in both space and time results in arrest of collapse, suppression…
