    "abstract": "We employ the Q representation to study the non-classical correlations that\nare present from below to above-threshold in the degenerate optical parametric\noscillator. Our study shows that such correlations are present just above\nthreshold, in the regime in which stripe patterns are formed, but that they\nalso persist further above threshold in the presence of spatially disordered\nstructures.",
