Composite band-gap solitons in nonlinear optically induced lattices

Desyatnikov, Anton S; Ostrovskaya, Elena; Kivshar, Yuri; Denz, Cornelia


We introduce novel optical solitons that consist of a periodic and a spatially localized component coupled nonlinearly via cross-phase modulation. The spatially localized optical field can be treated as a gap soliton supported by the optically induced nonlinear grating.We find different types of these bandgap composite solitons and demonstrate their dynamical stability.
