| Abstract: | We report on the experimental characterization of domain wall dynamics in a photorefractive resonator in a degenerate four-wave mixing configuration. We show how the non-flat profile of the emitted field affects the velocity of domain walls as well as the variations of intensity and phase gradient during their motion. We find a clear correlation between these two last quantities that allows the experimental determination of the chirality that governs the domain walls’ dynamics. PACS 42.65.Sf; 47.54.+r; 42.65.Hw |
