    "abstract": "We describe theoretically the quantum properties of atype-II Optical\nParametric Oscillator containing a birefringent plate which induces a linear\ncoupling between the orthogonally polarized signal and idler beams and results\nin phase locking between these two beams. As in a classical OPO, the signal and\nidler waves show large quantum correlations which can be measured\nexperimentally due to the phase locking between the two beams. We study the\ninfluence of the waveplate on the various criteria characterizing quantum\ncorrelations. We show in particular that the quantum correlations can be\nmaximized by using optimized quadratures.",
