Vorticity cutoff in nonlinear photonic crystals
Albert Ferrando, Mario Zacares, Miguel-Angel Garcia-March
Using group theory arguments, we demonstrate that, unlike in homogeneous media, no symmetric vortices of arbitrary order can be generated in two-dimensional (2D) nonlinear systems…
Nodal solitons and the nonlinear breaking of discrete symmetry
A. Ferrando, M. Zacares, P. Andres +2
We present a new type of soliton solutions in nonlinear photonic systems with discrete point-symmetry. These solitons have their origin in a novel mechanism of breaking of discrete…
Forward-backward equations for nonlinear propagation in axially-invariant optical systems
Albert Ferrando, Mario Zacares, Pedro Fernandez de Cordoba +2
We present a novel general framework to deal with forward and backward components of the electromagnetic field in axially-invariant nonlinear optical systems, which include those h…
