Highly efficient integrated single photon sources matched to atomic and molecular transitions

Highly efficient integrated single photon sources, which match the wavelengths and linewidths of cesium and rubidium transitions, will be implemented based on a versatile aluminum nitride platform. By means of spatial-mode multiplexing of up to eight sources on one chip, we aim to realize efficiencies above 90 %. Storage and retrieval of single narrowband photons in an atomic quantum memory will be demonstrated.
