    "abstract": "We explore in detail the possibility of generation of continuous-variable\n(CV) entangled states of light fields with well-localized phases. We show that\nsuch quantum states, called entangled self-phase locked states, can be\ngenerated in nondegenerate optical parametric oscillator (NOPO) based on a\ntype-II phase-matched down-conversion combined with polarization mixer in a\ncavity. A quantum theory of this device, recently realized in the experiment,\nis developed for both sub-threshold and above-threshold operational regimes. We\nshow that the system providing relative phase coherence between two generated\nmodes also exhibits different types of quantum correlations between photon\nnumbers and phases of these modes. We quantify the entanglement as two-mode\nsqueezing and show that CV entanglement is realized for both unitary,\nnon-dissipative dynamics and for dissipative NOPO in the entire range of pump\nfield intensities.",
