One Molecule Delivered 100 Million Photons a Second
A cryogenic antenna collected 97% of the emitter's light while preserving high purity and indistinguishability.
Summary
A cryogenic antenna collected 97% of the emitter's light while preserving high purity and indistinguishability.
Researchers integrated a single dibenzoterrylene molecule with a planar metallo-dielectric antenna and directed its cryogenic emission into collection optics. The device delivered 100 million photons per second into the first lens with 97% collection efficiency, while the authors measured 91.2% photon indistinguishability and 97.7% single-photon purity under continuous-wave and pulsed excitation. The result is a laboratory demonstration from one organic emitter, not yet a scalable quantum-photonic system, but it combines rate, collection and photon quality in one molecular source.
Why it matters
