Stable multicolor periodic-wave arrays
arXiv:physics/0501076 · doi:10.1103/PhysRevLett.92.033901
Abstract
We study the existence and stability of cnoidal periodic wave arrays propagating in uniform quadratic nonlinear media and discover that they become completely stable above a threshold light intensity. To the best of our knowledge, this is the first example in physics of completely stable periodic wave patterns propagating in conservative uniform media supporting bright solitons.
