Abstract
We investigate discrete soliton propagation in a waveguide array with periodically modulated coupling constants. If the modulation wave vector coincides with that of an internal mode, the respective bound state of the soliton is excited. Eventually, growing internal vibrations may result in a transverse motion or in a resonant splitting of the soliton.
