Abstract
Light-matter interaction on the level of single emitters and single photons has attracted significant scientific interest in recent years. Of particular interest is strong coupling of single emitters in solid state systems and its application to quantum information processing. Due to the enormous progress in semiconductor technology it has become feasible to demonstrate strong coupling of single quantum dots in high-Q microcavity systems [1–3]. Although it has been argued in these studies that it is very unlikely that several degenerated quantum dots contributed to the observed Rabi-splitting, it was not verified that the system had one and only one emitter. In this work we present proof that the emission from a strongly-coupled QD-microcavity system is dominated by a single quantum emitter.
