We study modes trapped in a rotating ring carrying the self-focusing (SF) or self-defocusing
(SDF) cubic nonlinearity and double-well potential cos 2 θ, where θ is the angular …

We study two-component solitons and their symmetry-breaking bifurcations (SBBs) in
linearly coupled photonic systems with a spatially inhomogeneous strength of the coupling …

We construct families of discrete solitons (DSs) in an array of self-defocusing waveguides
with an embedded parity-time-(PT-) symmetric dimer, which is represented by a pair of …

An optical four-level atomic discrete system in a solid through optical induction is proposed.
A theoretical scheme to produce lattice solitons (LSs) in the system is presented by means of …

We demonstrate an optical diode by building a domain wall with one-dimensional
waveguide array. The domain wall can be described by dividing the one-dimensional …

We study large-amplitude one-dimensional solitary waves in photonic crystals featuring

We study the fundamental modes trapped in a rotating ring with the local strength of the
linear and nonlinear potentials modulated as V (θ− ωz) and− V (θ− ωz), respectively, where …

Anderson location is an important wave phenomenon when the system contains disorder.
Anderson location of light is a significant topic in optical science. Arrays of evanescently …
