    "abstract": "We show that two evanescently coupled $\\chi^{(2)}$ parametric downconverters\ninside a Fabry-Perot cavity provide a tunable source of quadrature squeezed\nlight, Einstein-Podolsky-Rosen correlations and quantum entanglement. Analysing\nthe operation in the below threshold regime, we show how these properties can\nbe controlled by adjusting the coupling strengths and the cavity detunings. As\nthis can be implemented with integrated optics, it provides a possible route to\nrugged and stable EPR sources.",
