High efficient localized photon sources

The goal of this project is the development of a novel, hybrid and scalable quantum photonic circuit that enable the generation of tunable, brightness and indistinguishable single photons on-demand by the deterministically integration of III-V quantum emitters coupled to a planar hyperbolic metamaterial (HMM) resonator-antenna.

The implementation of the multilayered HMM over the semiconductor quantum dots (QDs) will be carry out by Micro/Nano Litography.

The innovative design of this proposal will enable to ensure the coupling between the emitter and far-field radiation channels and will provide extremely high Purcell factor and brightness enhancement.

While single emitters coupled to plasmonic waveguides have been widely studied, there are no experiments with HMM Resonator-Antenna in the literature, even when it is proved that is compatible with a wide variety of sources and capable of room temperature operation due to the broad bandwidth enhancement of spontaneous emission and directional photon emission.

Finally, HELPS project will contribute to the understanding of the novel applications and functionalities of HMM coupled to semiconductors nanomaterials.
