Abstract
We have investigated theoretically and experimentally the emission
of QD-cavity systems for different coupling strength and a wide range of
exciton-photon mode detunings controlled by temperature variation in the
range of 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 QD exciton or via
cavity mode. Particularly, in the case of nonresonant cavity mode excitation
the emission line becomes split in two asymmetric lines already in the weak
coupling regime.
