N2 - Deterministic techniques enabling the implementation and engineering of bright and coherent solid-state quantum light sources are key for the reliable realization of a next generation of quantum devices. Such a technology, at best, should allow one to significantly scale up the number of implemented devices within a given processing time. In this work, we discuss a possible technology platform for such a scaling procedure, relying on the application of nanoscale quantumdot imaging to the pillar microcavity architecture, which promises to combine very high photon extraction efficiency and indistinguishability. We discuss the alignment technology in detail,and present the optical characterization of a selected device which features a strongly Purcell enhanced emission output. This device, which yields an extraction efficiency of h = (49 ± 4) %, facilitates the emission of photons with (94 ± 2.7) % indistinguishability.
