We apply our recently developed theory of frequency-filtered and
time-resolved N-photon correlations (del Valle et al 2012 Phys. Rev. Lett.
109 183601) to study the two-photon spectra of a variety of systems of
increasing complexity: single-mode emitters with two limiting statistics (one
harmonic oscillator or a two-level system) and the various combinations that
arise from their coupling. We consider both the linear and nonlinear regimes
under incoherent excitation. We find that even the simplest systems display a
rich dynamics of emission, not accessible by simple single-photon spectroscopy.
In the strong coupling regime, two-photon emission processes involving
virtual states are revealed. Furthermore, two general results are unravelled by
two-photon correlations with narrow linewidth detectors: (i) filtering-induced
bunching and (ii) breakdown of the semi-classical theory. We show how to
overcome the latter in a fully quantized picture
