    "abstract": "We investigate a compact source of entanglement. This device is composed of a\npair of linearly coupled nonlinear waveguides operating by means of degenerate\nparametric downconversion. For the vacuum state at the input the generalized\nsqueeze variance and logarithmic negativity are used to quantify the amount of\nnonclassicality and entanglement of output beams. Squeezing and entanglement\ngeneration for various dynamical regimes of the device are discussed.",
