  • Patent number: 11309684
    Abstract: The invention relates to coherent single photon sources that provide photons with a high degree of indistinguishability. It is a disadvantage of single photon sources based on QDs in nanophotonic structures that, even at low temperatures, acoustic vibrations interact with the QDs to reduce the coherence of the emitted spectrum. The invention uses mechanical clamping of the nanostructure to damp vibrations leading to a weaker QD—phonon coupling and a higher degree of indistinguishability between successively emitted photons. The clamp is mechanically connected to the length of the photonic nanostructure and has a stiffness and a size sufficient to suppress low frequency vibrations (??10 GHz) in a combined structure of the clamp and the nanostructure.
