Spatial placement of these dots is controlled using a directed self-assembly technique that leads naturally to atomically-smooth ridge waveguide sidewalls. Theoretical analysis shows that this PC-ridge waveguide system provides broadband Purcell factor enhancement for planar collection and guidance of emitted single-photons. We investigate the pairwise interaction of single QDs using this waveguide system.
