Résumé : We demonstrate the existence of breathing dissipative light bullets in a birefringent optical resonator filled with Kerr media. The propagation of light inside the cavity for each polarized component, which is coupled by cross-phase modulation, is described by the coupled Lugiato–Lefever equations. The space–time dynamics of breathing light bullets are described using Stokes parameters and frequency spectra.
