  bibo_abstract:
  - <jats:p>In this paper, we theoretically study the spectral and temporal properties
    of pulsed spontaneous parametric down-conversion (SPDC) generated in lossy waveguides.
    Our theoretical approach is based on the formalism of Gaussian states and the
    Langevin equation, which is elaborated for weak parametric down-conversion and
    photon-number-unresolved click detection. Using the example of frequency-degenerate
    type-II SPDC generated under the pump-idler group-velocity-matching condition,
    we show how the joint-spectral intensity, mode structure, normalized second-order
    correlation function, and Hong-Ou-Mandel interference pattern depend on internal
    losses of the SPDC process. We found that the joint-spectral intensity is almost
    insensitive to internal losses, while the second-order correlation function shows
    a strong dependence on them, being different for the signal and idler beams in
    the presence of internal losses. Based on the sensitivity of the normalized second-order
    correlation function, we show how its measurement can be used to experimentally
    determine internal losses.</jats:p>@eng
