•Here, we discuss the realization of systems of site-controlled QDs integrated within photonic crystal (PhC) membrane cavities.•Systems comprising 2, 3 or 4 pyramidal QDs integrated within L7 PhC membrane cavities are realized and characterized structurally and optically.•Using micro-photoluminescence (PL) spectroscopy we probe the optical coupling of each QD in a given system to a common, confined optical mode of the PhC cavity.
We describe the fabrication, epitaxial growth and photoluminescence (PL) spectra of systems of site-controlled pyramidal quantum dots (QDs) integrated with photonic crystal (PhC) membrane cavities. The spectra of the individual QDs are characterized by scanning micro-PL spectroscopy, and the cavity modes are identified by polarization-resolved PL measurements and modeling. Weak coupling of systems incorporating up to four identifiable QDs with single modes of the PhC cavities is demonstrated.
