A skyrmion is a topologically stable field configuration. A non-local skyrmion, which has been hitherto elusive in condensed-matter physics, is realized by using entangled photons with a non-trivial topology. The connection between the notions of topology and entanglement is investigated, revealing topological invariance even when entanglement is fragile.
Ammonium bromide is shown to passivate deep traps on FAPbBr3 surfaces, improving the charge collection efficiency to near unity in perovskite gamma-ray devices. The approach yielded tenfold improvements in dark current, and the energy resolution of 137Cs spectra acquired using FAPbBr3 detectors was improved from 5.7% to 1.7%.
Nature Photonics spoke with Rüdiger Paschotta, the founder of RP Photonics, about his online encyclopedia of photonics, the motivation behind it and future plans for the project.
Acoustic modulation of atmospheric air enables the deflection of laser pulses with a peak power of 20 gigawatts, expanding the acousto-optics toolbox to high-power laser manipulation in ambient air.
With many exotic electromagnetic effects, metamaterials are now being exploited in real-world biomedical applications, with expected impacts in healthcare.
Controlling the intrinsic doping of lead-free perovskites enables near-infrared LEDs emitting at 948 nm with a peak radiance of 226 W sr–1 m–2 and a half-lifetime of 39.5 h.
Exploiting the signal correlation between multiple quantum sensors enables measuring overlapping signals from multiple targets, as demonstrated by imaging point defects in a diamond with an accuracy of 1.7 nm.
A terahertz focal-plane array based on a two-dimensional array of plasmonic photoconductive nanoantennas offers high-quality imaging in the terahertz region.
Electrically injected charges can effectively contribute to optical gain in perovskite light-emitting diodes under optical and electrical co-excitation.
Dipole–dipole interactions in mixed-phase CdZnSeS quantum dots enable the effective orientation of the quantum dots and improved photon out-coupling when employed in a light emitting diode.
Silver telluride quantum dots are employed in shortwave-infrared photodetectors and in monolithically integrated imagers that are free from toxic heavy metals and fully solution processable.
Advances in the understanding of optical skyrmions, within a unified topological framework, are reviewed. The field structure of such optical quasiparticles, and their topological characteristics, may be useful for fields ranging from imaging to quantum technologies.
The progress made in developing light-emitting technologies that are wearable, attachable or implantable is reviewed and potential applications and challenges are discussed.
A new form of chirped amplification with two different nonlinear crystals can generate high-energy, single-cycle laser pulses with terawatt-level peak powers.
A coherent microwave-to-optical conversion scheme, previously feasible only under cryogenic environments, has now been expanded to ambient conditions by using Rydberg atoms.
