In recent years, there has been considerable interest in the study of wave propagation in
nonlinear photonic lattices. The interplay between nonlinearity and periodicity has led …

We study linear and nonlinear wave dynamics in the Lieb lattice, in the vicinity of an
intersection point between two conical bands and a flat band. We define a pseudospin …

The linear spectrum and corresponding Bloch modes of shallow honeycomb lattices near
Dirac points are investigated. Via perturbation theory, the dispersion relation is found to …

We study the coupling between backward-and forward-propagating wave modes, with the
same group velocity, in a composite right-and left-handed nonlinear transmission line. Using …

We consider the nonlinear Dirac equation in 1+ 1 dimension with scalar-scalar self
interaction g 2 κ+ 1 (Ψ¯ Ψ) κ+ 1 and with mass m. Using the exact analytic form for rest frame …

We investigate linear and nonlinear evolution dynamics of light beams propagating along a
dislocated edge-centered square lattice. The band structure and Brillouin zones of this novel …

Wave dynamics in topological materials has been widely studied recently. A striking feature
is the existence of robust and chiral wave propagations that have potential applications in …

We fabricate honeycomb and related photonic lattices in a nonlinear crystal with a simple
method that is based on the optical Fourier transformation through an amplitude mask (six …

We report on theoretical and experimental investigations of optical wave propagations in two-
dimensional photonic lattice structures formed in a holographic polymer-dispersed liquid …

We investigate the conical diffraction in Kagome lattice (KL) theoretically and numerically.
According to the plane wave expansion method, we obtain the band structure of KL, in which …
