Quantized vortices are observed in a Bose–Einstein condensate.

A miniaturized ultraviolet spectral imager based on a cascaded AlGaN/GaN photodiode with a compositionally graded active region enables spectral imaging in the 250–365 nm range. The device allows the classification of different types of organics, such as oils and milk, in a single-shot imaging modality.

By exploiting an optical thermodynamic framework, researchers demonstrate universal routing of light. Specifically, light launched into any input port of a nonlinear array is universally channelled into a tightly localized ground state. The principles of optical thermodynamics demonstrated may enable new optical functionalities.

Irradiation with a pulsed Laguerre–Gaussian laser beam of charge one enables correcting the third-order spherical aberration of an electron beam.

Researchers observe directional strong coupling on the nanoscale between hyperbolic phonon polaritons and pentacene molecules.

Although typical microwave isolators provide 20 dB of isolation, a topological isolator—based on a one-way edge waveguide—enables 100 dB isolation due to the near-complete absorption of the backward-propagating mode. In theory, 200 dB of isolation is possible within a single-wavelength-size device.

In this Focus issue we highlight a selection of recent developments in super-resolution microscopy.

Super-resolution microscopy offers valuable tools to tackle biological questions. Nature Photonics spoke with Markus Sauer, from the University of Würzburg, about the advantages and outstanding challenges of super-resolution microscopy for biological applications.

The performance of super-resolution microscopy is continuously improving. Nature Photonics interviewed Stefan Hell, from the Max Planck Institute for Multidisciplinary Sciences, about key milestones in the field, current capabilities of MINFLUX and what remains to be excited about.

Champion experimentalist of quantum optics and squeezed-light pioneer has sadly passed away.

Sir Peter Knight, described as "one of the UK’s most influential scientists and leaders of scientific policy" by his peers, tells Nature Photonics about the many hats he is wearing now in pushing quantum research and technologies in the UK and beyond.
