We demonstrate that symmetry breaking in intra-cavity vectorial second harmonic generation may cause the formation of different types of localized structures. Moving as well as resting cavity solitons are observed and the interaction between them is studied.

By operating an AlGaAs waveguide array at the half band gap, we experimentally demonstrate basic features of discrete systems, which do not appear in the corresponding continuous counterpart - the slab waveguide. Under selected initial conditions, we observed nonlinearly induced locking of an initially moving soliton to the input waveguide. If the power is even higher, originally locked beams start to move again, but in a direction opposite to the initial tilt.
