We study, by time-resolved photoluminescence, the radiative lifetime of InAs quantum boxes (QBs) placed in the core of small volume and high finesse GaAs/AlAs pillar microresonators. The spontaneous emission rate of the QBs, which are on-resonance with a cavity mode, is found to be up to five time l

GaAs=AlAs pillar microcavities containing an array of InAs quantum boxes in their core region have been fabricated by molecular beam epitaxy, electron-beam lithography and reactive ion etching. By placing this broadband light emitter in the cavity, we can probe precisely by photoluminescence the mod
