We apply our recently developed theory of frequency-filtered and time-resolved N-photon correlations [1] to study the two-photon spectra of a variety of systems of increasing complexity: single mode emitters and the various combinations that arise from their coupling. We consider both the linear and nonlinear regimes under incoherent excitation [2]. 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, novel two-photon emission processes involving virtual states are revealed which can be exploited for two-photon state generation [3].
