The ability to control the nucleation site of a single quantum dot will have a profound effect oil the development of quantum dot-based photonic devices. The deterministic approach will provide a truly scalable technology that can take full advantage of conventional semiconductor processing for device fabrication In this review, we discuss the progress towards the integration of deterministically nucleated single quantum dots with top-down quantum optical devices targeting telecommunication wavelengths Advances in site-controlled quantum dot nucleation using, selective-area epitaxy now makes it possible to position quantum dots at predetermined positions oil a substrate in registry with alignment markers This, in turn, has allowed for devices fabricated in subsequent processing steps to be aligned to individual quantum dots The specific devices being targeted are gated-single dots and Coupled dot-cavity systems which are key components of efficient sources of single photons and entangled photon pairs
