Nanophotonics has been rapidly developing in recent years as the quest for integrated devices enabling the generation, manipulation and detection of single photons for light-based quantum information processing and cryptography is heavily pursued. A huge step forward in this regard is the monolithic integration of an electrically driven excitation source driving a non-classical light source on a single chip. We report on recent progress with a novel device incorporating semiconductor quantum dots embedded in micropillar cavities, which can be excited optically through the in-plane whispering gallery mode laser emission of a nearby electrically driven micropillar. The feasibility of such an approach for on-demand single and indistinguishable photon generation utilizing cavity-quantum electrodynamic effects as well as on-chip resonance fluorescence is clearly demonstrated by recent results.
