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…
Light bullets in Su-Schrieffer-Heeger photonic topological insulators
Sergey K. Ivanov, Yaroslav V. Kartashov, Lluis Torner
We introduce a different class of thresholdless three-dimensional soliton states that form in higher-order topological insulators based on a two-dimensional Su-Schrieffer-Heeger ar…
