We introduce a novel mode-locking scheme based on polariton-polariton interactions and we demonstrate its operation in a $60 \ \mu m-$long GaN-based waveguide cavity. The exciton-polariton active layer acts both as a gain medium and as a self-focusing medium with a large Kerr-like nonlinearity. The monitoring of the cavity free spectral range across the lasing threshold evidences the linearization of the strongly nonlinear mode dispersion due to self-phase modulation. The Gross-Pitaevskii equation for the coupled exciton and photon fields taking into account the exact cavity geometry, predicts the appearance of optical pulses within the cavity that correspond to optical solitons. Pulses widths are about 100 fs, both in theory and experiment.
