    "abstract": "A new device to generate polarization-entangled light in the continuous\nvariable regime is introduced. It consists of an Optical Parametric Oscillator\nwith two type-II phase-matched non-linear crystals orthogonally oriented,\nassociated with birefringent elements for adjustable linear coupling. We give\nin this paper a theoretical study of its classical and quantum properties. It\nis shown that two optical beams with adjustable frequencies and well-defined\npolarization can be emitted. The Stokes parameters of the two beams are\nentangled. The principal advantage of this setup is the possibility to directly\ngenerate polarization entangled light without the need of mixing four modes on\nbeam splitters as required in current experimental setups. This device opens\nnew directions for the study of light-matter interfaces and generation of\nmultimode non-classical light and higher dimensional phase space.",
