Solitons, nonlinear self-trapped wavepackets, have been extensively studied in many and
diverse branches of physics such as optics, plasmas, condensed matter physics, fluid …

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 …

Photonic integrated circuits are a key component 1 of future telecommunication networks,
where demands for greater bandwidth, network flexibility, and low energy consumption and …

Recently, the concept of skin effect has gained considerable attention in the context of non-
Hermitian photonics. The experimental realization of Hatano–Nelson systems in optical …

We present a brief overview of the basic concepts and important experimental observations
of the effect of light localization near the surfaces of truncated periodic photonic structures. In …

We study the effects associated with spatiotemporal light localization near the edge of a
semi-infinite array of weakly coupled nonlinear optical waveguides. It was shown earlier that …

We introduce an experimental approach to realize truncated 2D deterministic aperiodic
photonic structures using the interference of two mutually coherent Weber beams. The …

Discrete spatial solitons traveling along the interface between two dissimilar one-
dimensional arrays of waveguides were observed for the first time. Two interface solitons …

We study the properties of two-color nonlinear localized modes which may exist at the
interfaces separating two different periodic photonic lattices in quadratic media, focusing on …

In a numerical study, we observe Anderson localization of surface modes at the interface
between a linear and a nonlinear dielectric medium, containing an optically induced …
