Abstract |
|
|
| Using computational methods, the numerical existence and nonlinear stability of fundamental solitons in saturable media on
crystal and certain type of quasicrystal lattices are investigated. In a certain parameter regime of the lattice depth and the propagation
constant, the first nonlinear band-gap structures are obtained and the effect of the DC bias field (external electric field) and the lattice
depth to the gap width are analyzed. |
