We employ a quasimode representation of the adjoint master equation to study nonlinear pair-generation dynamics via spontaneous four-wave mixing in coupled-cavity systems in the presence of scattering loss. Perturbative analytic solutions for signal and idler photon-number operators are derived, which enable us to examine the effect of scattering loss on pair-generation dynamics. In particular, for a simple three-mode system, we show that any loss mismatch for the signal and idler photons increases the probability of finding unpaired photons. While decreasing the loss rates for signal and idler photons increases the pair signal brightness, it also results in higher generation rates for multiple pairs in the system, which can result in lower operational signal-to-noise ratios.
