Abstract

The formation of nonlinearly managed spatial solitons in Kerr-type nonlinear media with transverse periodic modulation of the refractive index is considered. The phenomenon of resonant enhancement of lattice soliton amplitude oscillations is reported. We show how the tunable discreteness and competition between such characteristic scales as the beam width and the lattice period influence propagation dynamics and properties of breathing lattice solitons.
