Abstract: We report experimental evidence of temporal coexistence and alternation of patterns having different scales in a nonlinear optical system formed by a Kerr-like medium with feedback. Time coexistence occurs via spatial segregation of the different patterns in different domains, separated by topological defects. A simple theoretical model yields predictions in good agreement with the experimental results.
