The emission characteristics of a system of one quantum dot (QD) nonresonantly coupled to two distinct detuned modes of a surrounding microcavity have been investigated, revealing strong interconnection in terms of photon anti-correlation in QD-mode and mode-mode cross correlations. Temperature-dependent lifetime measurements demonstrate that the QD emission dynamics is transferred to the mode channels through the process of nonresonant coupling, whereas the short coherence time of mode emission stays unperturbed by the QD-mode detuning. Power-dependent studies under pure-resonant QD excitation have traced the strong emitter-mode coupling to both an excited and the fundamental micropillar mode with spectral detunings of up to 3.7 meV.
