    "abstract": "We describe theoretically the main characteristics of the steady state regime\nof a type II Optical Parametric Oscillator (OPO) containing a birefringent\nplate. In such a device the signal and idler waves are at the same time\nlinearly coupled by the plate and nonlinearly coupled by the $\\chi^{(2)}$\ncrystal. This mixed coupling allows, in some well-defined range of the control\nparameters, a frequency degenerate operation as well as phase locking between\nthe signal and idler modes. We describe here a complete model taking into\naccount all possible effects in the system, \\emph{i.e.} arbitrary rotation of\nthe waveplate, non perfect phase matching, ring and linear cavities. This model\nis able to explain the detailed features of the experiments performed with this\nsystem.",
