Phys. Rev. Lett. 103, 027401 (2009) [4 pages]Origin of the Optical Emission within the Cavity Mode of Coupled Quantum Dot-Cavity SystemsReceived 13 March 2009; published 6 July 2009 The origin of the emission within the optical mode of a coupled quantum dot-micropillar system is investigated. Time-resolved photoluminescence is performed on a large number of deterministically coupled devices in a wide range of temperature and detuning. The emission within the cavity mode is found to exhibit the same dynamics as the spectrally closest quantum dot state. Our observations indicate that fast dephasing of the quantum dot state is responsible for the emission within the cavity mode. An explanation for recent photon correlation measurements reported on similar systems is proposed. © 2009 The American Physical Society URL:
