Paper Abstract

In this paper we derive the eigenmodes for the nonlinear self- organization of light in photorefractive potassium niobate. This is the first step of the two-step process involved in the self-organization of light into a hexagonal pattern observed in this and other materials. Complete steady state solutions are derived and amplitude and phase variations of the counterpropagating main beam and its spatial sidebands (responsible for ring formation) are shown. Our computations show the bifurcation diagrams of the amplitudes and phases as a function of the photorefractive gain parameter. Dependence of the results on the amount of linear scattering is also demonstrated.
