Abstract By calculating correlation spectra of the output fields, we show theoretically that two evanescently coupled χ(2) second harmonic generators inside a Fabry–Perot cavity provide a tunable source of quadrature squeezed light, Einstein–Podolsky–Rosen correlations and quantum entanglement. Unlike systems using coupled downconverters, second harmonic generation has no oscillation threshhold, so that the entangled fields become macroscopically occupied as soon as the pumping fields are turned on. This system also gives two frequencies at which the entangled fields can have macroscopic intensity. We show how the entanglement properties can be controlled by adjusting the pumping, the coupling strengths and the cavity detunings.
