摘要
Modification of the spontaneous emission properties of a single InAs quantum dot is demonstrated using a epitaxial distributed-Bragg reflector microcavity that has been processed into posts with diameters ranging in size from 20 mum to 0.5 mum. The micropost structure isolates single quantum dots within the microcavity resonance, and creates a 3-dimensionally (3D) confined optical cavity. The discrete mode structure of the 3D cavity is observed, as well as the coupling of a single quantum dot to one of these modes in the weak coupling cavity QED regime.
