【 摘 要 】

Single photon emission by an InAs/GaAs quantum dot weakly coupled to a photonic crystal microcavity has been studied as a function of energy detuning. Precise and continuous control of the photon statistics as well as of the linear polarization emission angle is achieved simply by changing the energy detuning between the exciton and the cavity mode. A continuous decrease of the antibunching time, the bunching amplitude and the g(2)(0) value is observed as the detuning is decreased at constant excitation rate, due to the detuning-dependent Purcell effect.
