Up to six photons in a Greenberger–Horne–Zeilinger state are sequentially generated by using a Rydberg superatom—a mesoscopic atomic ensemble under the condition of strong Rydberg blockade. The efficiency scaling factor for adding one photon is 0.27.

Near-infrared perovskite light-emitting diodes with extrapolated device lifespans on the scale of years are achieved by the use of a dipolar molecular stabilizer.

A tilted plasmonic nanocavity enables shortening of the luminescence decay time of a rare-earth-doped nanoparticle to sub-50 ns. High quantum efficiency enhancement, chiral polarization and directional far-field emission are maintained.

An array of ⁸⁷Rb atoms with inter-atomic distances of 1.5 μm is prepared by holographic optical tweezers. When a pair of nearby ⁸⁷Rb atoms is optically excited to a Rydberg state, the energy exchange between the atoms is observed on a timescale of nanoseconds.

Lanthanide nanotransducers are developed to detect broadband incoherent mid-infrared radiation in the 4–11 μm spectral window by ratiometric luminescence measurements.

Researchers exploit the quadratic nonlinearity of lithium niobate nanowaveguides and demonstrate cavity-free all-optical switching. Switching energies down to 80 fJ, switching times down to ~46 fs and energy–time products of 3.7 × 10⁻²⁷ J s are shown.

Three pioneers of attosecond physics share the 2022 Wolf Prize in Physics.

The 2022 Wolf Prize in Physics has been awarded to Paul Corkum, Anne L’Huillier and Ferenc Krausz for their pioneering contributions to ultrafast laser science. Nature Photonics spoke to them about the milestones, challenges and future opportunities for the field.

In order to simplify and streamline our processes, Nature Photonics is moving to a single format for its primary research submissions

A heat-powered emitter can sometimes exceed the Planck thermal-emission limit. We clarify when such super-Planckian emission is possible, arguing that far-field super-Planckian emission requires a distribution of energy that is not consistent with a unique temperature, and therefore the process should not be called ‘thermal emission’.

Nature Photonics spoke to Hillel Adesnik from UC Berkeley about the benefits of using photonic techniques in optogenetics and the key challenges laying ahead.

The field of flat lens research brings innovative nanophotonic design concepts to the world of macro-optics. However, when evaluating the performance of these lenses a lack of consistency prevents proper comparison of competing technologies. This problem can be solved by using methods developed in industry for conventional lenses.
