We provide an overview of recent experimental and theoretical developments in the area of
optical discrete solitons. By nature, discrete solitons represent self-trapped wavepackets in …

We present a progress overview focused on the recent theoretical and experimental
advances in the area of soliton manipulation in optical lattices. Optical lattices offer the …

We propose solitons in a photonic topological insulator: self-localized wave packets forming
topological edge states residing in the bulk of a nonlinear photonic topological insulator …

We theoretically introduce a type of topological dipole soliton propagating in a Floquet
topological insulator based on a kagome array of helical waveguides. Such solitons …

We study the effect of nonlinearity on systems with periodic parity-time (PT) symmetry, and
show that nonlinearity can transform the system from broken to full PT symmetry and vice …

A new numerical scheme for computing self-localized states—or solitons—of nonlinear
waveguides is proposed. The idea behind the method is to transform the underlying …

We study various families of two-dimensional discrete or lattice solitons, and show that they
are possible only when their power level exceeds a critical threshold. In addition, we show …

We present the first study of subwavelength discrete solitons in nonlinear metamaterials:
nanoscaled periodic structures consisting of metal and nonlinear dielectric slabs. The …

We put forward the existence of surface gap solitons at the interface between uniform media
and an optical lattice with defocusing nonlinearity. Such new type of solitons forms when the …
