Coupled-mode theory for spatial gap solitons in optically-induced lattices
Boris A. Malomed, Elena A. Ostrovskaya, Yuri S. Kivshar
We develop a coupled-mode theory for spatial gap solitons in the one-dimensional photonic lattices induced by interfering optical beams in a nonlinear photorefractive crystal. We d…

Stability and collisions of moving semi-gap solitons in Bragg cross-gratings
T. Mayteevarunyoo, Boris A. Malomed, P. L. Chu +1
We report results of a systematic study of one-dimensional four-wave moving solitons in a recently proposed model of the Bragg cross-grating in planar optical waveguides with the K…
