Multicolor vortex solitons in two-dimensional photonic lattices
Zhiyong Xu, Yaroslav V. Kartashov, Lucian-Cornel Crasovan +2
We report on the existence and stability of multicolor lattice vortex solitons constituted by coupled fundamental frequency and second-harmonic waves in optical lattices in quadrat…
Stable ring vortex solitons in Bessel optical lattices
Yaroslav V. Kartashov, Victor A. Vysloukh, Lluis Torner
Stable ring vortex solitons, featuring a bright-shape, appear to be very rare in nature. However, here we show that they exist and can be made dynamically stable in defocusing cubi…
Soliton spiraling in optically-induced rotating Bessel lattices
Yaroslav V. Kartashov, Victor A. Vysloukh, Lluis Torner
We address soliton spiraling in optical lattices induced by multiple coherent Bessel beams and show that the dynamical nature of such lattices make them able to drag different soli…
Spatiotemporal discrete multicolor solitons
Zhiyong Xu, Yaroslav V. Kartashov, Lucian-Cornel Crasovan +2
We have found various families of two-dimensional spatiotemporal solitons in quadratically nonlinear waveguide arrays. The families of unstaggered odd, even and twisted stationary…
Stable soliton complexes and azimuthal switching in modulated Bessel optical lattices
Yaroslav V. Kartashov, Alexey A. Egorov, Victor A. Vysloukh +1
We address azimuthally modulated Bessel optical lattices imprinted in focusing cubic Kerr-type nonlinear media, and reveal that such lattices support different types of stable soli…
Stabilization of vector solitons in optical lattices
Yaroslav V. Kartashov, Anna S. Zelenina, Victor A. Vysloukh +1
We address the properties and dynamical stability of one-dimensional vector lattice solitons in Kerr-type cubic medium with harmonic transverse modulation of refractive index. We d…
Rotary dipole-mode solitons in Bessel photonic lattices
Yaroslav V. Kartashov, Alexey A. Egorov, Victor A. Vysloukh +1
We address Bessel photonic lattices of radial symmetry imprinted in cubic Kerr-type nonlinear media and show that they support families of stable dipole-mode solitons featuring two…
Soliton eigenvalue control with optical lattices
Yaroslav V. Kartashov, Lucian-Cornel Crasovan, Anna S. Zelenina +4
We address the dynamics of higher-order solitons in optical lattices, and predict their self-splitting into the set of their single-soliton constituents. The splitting is induced b…
Rotary solitons in Bessel photonic lattices
Yaroslav V. Kartashov, Victor A. Vysloukh, Lluis Torner
We introduce solitons supported by Bessel photonic lattices in cubic nonlinear media. We show that the cylindrical geometry of the lattice, with several concentric rings, affords u…
Soliton trains in photonic lattices
Yaroslav V. Kartashov, Victor A. Vysloukh, Lluis Torner
We address the formation and propagation of multi-spot soliton packets in saturable Kerr nonlinear media with an imprinted harmonic transverse modulation of the refractive index. W…
