  text: <jats:p>Uniaxial anisotropy in nonlinear birefringent crystals limits the
    efficiency of nonlinear optical interactions and breaks the spatial symmetry of
    light generated in the parametric down-conversion (PDC) process. Therefore, this
    effect is usually undesirable and must be compensated for. However, high gain
    may be used to overcome the destructive role of anisotropy in order to generate
    bright two-mode correlated twin-beams. In this work, we provide a rigorous theoretical
    description of the spatial properties of bright squeezed light in the presence
    of strong anisotropy. We investigate a single crystal and a system of two crystals
    with an air gap (corresponding to a nonlinear SU(1,1) interferometer) and demonstrate
    the generation of bright correlated twin-beams in such configurations at high
    gain due to anisotropy. We explore the mode structure of the generated light and
    show how anisotropy, together with crystal spacing, can be used for radiation
    shaping.</jats:p>

  text: "Measurement-induced nonclassical effects in a two-mode interferometer are\r\ninvestigated
    theoretically using numerical simulations and analytical results.\r\nWe demonstrate
    that for certain parameters measurements within the\r\ninterferometer lead to
    the occurrence of two-mode squeezing. The results\r\nstrongly depend on the detection
    probability, the phase inside the\r\ninterferometer, and the choice of the input
    states. The appropriate parameters\r\nfor maximized squeezing are obtained. We
    analyze the influence of losses and\r\nconfirm that the predicted effects are
    within reach of current experimental\r\ntechniques."
