We have investigated theoretically and experimentally the emission of (quantum dot-cavity) systems for different coupling strength and a wide range of exciton-photon mode detunings controlled by temperature variation in the range 10–45 K. Under close to resonance conditions, the radiation spectrum from the cavity emission becomes essentially dependent on the primary excitation path, which can be either via resonant quantum-dot exciton or via cavity mode. Particularly, in the case of nonresonant cavity mode excitation, the emission line becomes split into two asymmetric lines already in the weak coupling regime.
