Using time-resolved photoluminescence spectroscopy, we have studied the Purcell spontaneous emission enhancement provided by a novel type of microcavity that forms a fully buried, all-epitaxial semiconductor heterostructure. The quantum dot containing region and the cavity boundaries are simultaneously defined in a unique way and lead to spatially self-aligned emitters. We demonstrate post-growth control of the quality factor and the capability of directly imaging the spatial field distribution that critically impacts the Purcell effect.
