We show experimental and numerical results about attractive interactions between phase solitons in a strongly multimode semiconductor laser with injected signal. The formation of soliton bound states, or phase solitons with multiple chiral charge, is demonstrated and analyzed in terms of the (spatio-temporally resolved) phase dynamics of the system. Propagation velocity of phase solitons in the longitudinal cavity is studied, and a correlation is established with phase soliton size and total charge.
