Vortex twins and anti-twins supported by multi-ring gain landscapes
Olga V. Borovkova, Yaroslav V. Kartashov, Valery E. Lobanov +2
We address the properties of multi-vortex soliton complexes supported by multi-ring gain landscapes in focusing Kerr nonlinear media with strong two-photon absorption. Stable compl…
Bright solitons from defocusing nonlinearities
Olga V. Borovkova, Yaroslav V. Kartashov, Lluis Torner +1
We report that defocusing cubic media with spatially inhomogeneous nonlinearity, whose strength increases rapidly enough toward the periphery, can support stable bright localized m…
Algebraic bright and vortex solitons in defocusing media
Olga V. Borovkova, Yaroslav V. Kartashov, Boris A. Malomed +1
We demonstrate that spatially inhomogeneous defocusing nonlinear landscapes with the nonlinearity coefficient growing toward the periphery as [1+abs(r)]**a support one- and two-dim…
General quasi-non-spreading linear three-dimensional wave-packets
Olga V. Borovkova, Yaroslav V. Kartashov, Valery E. Lobanov +2
We introduce a general approach for generation of sets of three-dimensional quasi-non-spreading wavepackets propagating in linear media, also referred to as linear light bullets. T…
Rotating vortex solitons supported by localized gain
Olga V. Borovkova, Valery E. Lobanov, Yaroslav V. Kartashov +1
We show that ring-like localized gain landscapes imprinted in focusing cubic (Kerr) nonlinear media with strong two-photon absorption support new types of stable higher-order vorte…
