Floquet edge solitons in modulated trimer waveguide arrays
Shuang Shen, Yaroslav V. Kartashov, Yongdong Li +1
We show that one-dimensional Floquet trimer arrays with periodically oscillating waveguides support two different and co-existing types of topological Floquet edge states in two di…
Observation of solitons in oscillating waveguide arrays
Antonina A. Arkhipova, Yiqi Zhang, Yaroslav V. Kartashov +8
Floquet systems with periodically varying in time parameters enable realization of unconventional topological phases that do not exist in static systems with constant parameters an…
-solitons on a ring of waveguides
Sergey K. Ivanov, Yaroslav V. Kartashov
We study the existence and stability of -solitons on a ring of periodically oscillating waveguides. The array is arranged into Su-Schrieffer-Heeger structure placed on a ring, w…
Vortex solitons in moire optical lattices
Sergey K. Ivanov, Vladimir V. Konotop, Yaroslav V. Kartashov +1
We show that optical moire lattices enable the existence of vortex solitons of different types in self-focusing Kerr media. We address the properties of such states both in lattice…
Photonic Snake States in Two-Dimensional Frequency Combs
Salim B. Ivars, Yaroslav V. Kartashov, Pedro Fernández de Córdoba +3
Taming the instabilities inherent to many nonlinear optical phenomena is of paramount importance for modern photonics. In particular, the so-called snake instability is universally…
Observation of rotation-induced light localization in waveguide arrays
Chunyan Li, Antonina A. Arkhipova, Yaroslav V. Kartashov +8
We study both, experimentally and theoretically, propagation of light in the fs-laser written rotating square waveguide arrays and present the first experimental evidence of light…
