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 …

Over the last few years arrays of evanescently coupled waveguides have been brought into
focus as a particular representation of functionalized optical materials, in which the …

We provide what we believe to be the first experimental demonstration of linear Shockley-
like surface states in an optically induced semi-infinite photonic superlattice. Such surface …

A photonic analog of Klein tunneling for a relativistic electron across a potential step, based
on spatial light propagation in an engineered binary waveguide array, is proposed. Klein …

We study the formation of Shockley-like surface states and their transition into Tamm-like
surface states in an optically induced semi-infinite photonic superlattice. While perfect …

We study analytically and numerically the optical analog of the Jackiw-Rebbi states in
quantum-field theory. These solutions exist at the interface of two binary waveguide arrays …

A novel type of waves is examined in the context of non-Hermitian photonics. We can
identify a class of complex guided structures that support localized paraxial solutions whose …

We report on the experimental observation of two-dimensional solitons at the interface
between square and hexagonal waveguide arrays. In addition to the different symmetries of …

We present the discrete analog of Snell's refraction law at the interface between two
dissimilar waveguide arrays. Additionally, reflection and transmission coefficients for the …
