The discrete quantum nature of plasmons may be exploited to make efficient single-photon sources. Despite the losses associated with metallic resonators, advantages over dielectric counterparts exist when it comes to producing efficient quantum emitters.
An external 'tuning knob' by means of applying a transverse electric field has been experimentally demonstrated to modify the bandgap of black phosphorus, making the two-dimensional material practical for integration in functional nanodevices.
Two concurrent demonstrations of programmable photonic processors based on large meshes of interconnected waveguides on a silicon chip provide new hope for optical information processing.
Reports of photon–photon interaction experiments, novel imaging schemes and state-of-the-art mirrors were highlights of the recent International Conference on X-ray Optics and Applications in Yokohama, Japan.
The official opening of the SESAME synchrotron in Jordan on 16 May marked an important landmark for science in the Middle East. It is also set to become the world's first solar-powered accelerator.
More than 500 near-infrared laser photons are scattered by a single electron into a single X-ray photon. This is the first experimental evidence of high-order multiphoton Thomson scattering and validates the decades-old theoretical predictions.
An evanescent single-molecule biosensor that operates at the fundamental precision limit, allowing a four-order-of-magnitude reduction in optical intensity while maintaining state-of-the-art sensitivity, is demonstrated.
Methyl ammonium lead triiodide perovskite wafers for application in direct conversion X-ray detectors are fabricated by a room-temperature sintering process. A conversion efficiency of 2,527 mC Gyaircm–2 under 70 kVp X-ray exposure is obtained.
A large-scale, low-loss and phase-stable programmable nanophotonic processor is fabricated to explore quantum transport phenomena. The signature of environment-assisted quantum transport in discrete-time systems is observed for the first time.
