Latest Patents
Dreessen holds a patent for a coherent single photon source. This invention relates to sources that provide photons with a high degree of indistinguishability. A key disadvantage of existing single photon sources based on quantum dots (QDs) in nanophotonic structures is that acoustic vibrations can interact with the QDs, reducing the coherence of the emitted spectrum. Dreessen's invention employs mechanical clamping of the nanostructure to dampen vibrations, leading to a weaker QD-phonon coupling. This results in a higher degree of indistinguishability between successively emitted photons. The clamp is mechanically connected to the length of the photonic nanostructure and is designed to suppress low-frequency vibrations (ω ≤ 10 GHz) in a combined structure of the clamp and the nanostructure.
