Latest Patents

Tighineanu holds a patent for a coherent single photon source. This invention relates to coherent single photon sources that provide photons with a high degree of indistinguishability. A disadvantage of single photon sources based on quantum dots (QDs) in nanophotonic structures is that, even at low temperatures, acoustic vibrations interact with the QDs, reducing the coherence of the emitted spectrum. Tighineanu's invention utilizes 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 possesses sufficient stiffness and size to suppress low-frequency vibrations (ω ≤ 10 GHz) in a combined structure of the clamp and the nanostructure.
