Entanglement and the Einstein-Podolsky-Rosen paradox with coupled intracavity optical downconverters

M. K. Olsen, P. D. Drummond

We show that two evanescently coupled ${\chi }^{(2)}$ parametric downconverters inside a Fabry-Perot cavity provide a tunable source of quadrature squeezed light, Einstein-Podolsky-Rosen…
