Scientists in Europe have demonstrated experimentally how a continuous-wave source of entangled states can be used to discretely entangle two distant quantum bits (qubits) without the complex control ...

Researchers leverage the versatility of liquid crystals to enable the dynamic modulation of a nonlinear platform.

The 2026 Nobel Prize in Physiology or Medicine recognizes work at the crossroads of biology, genetics and optics and photonics. Karl Deisseroth, Peter Hegemann and Georg Nagel [Images, left to right: ...

The rapid proliferation of realistic AI-generated content has created an urgent need for reliable and robust deepfake ...

Mental health has long been a concern for early-career researchers, broadly defined as Ph.D. students and postdoctoral fellows, but the reach and severity of this problem have remained unclear. A new ...

Converting salty ocean water to freshwater helps meet the growing human and agricultural demand for the latter, but the desalination process has harmful byproducts: carbon dioxide and highly condensed ...

I pursued a Ph.D. in science because I love problem-solving, diving deep into how and why things work, and using knowledge to serve a broader social good. Yet during grad school, while studying the ...

In the latest installment of Journeys in Optics, OPN spoke with 2025 Optica Ambassador Andrea Pacheco, a Marie Skłodowska-Curie Actions Postdoctoral Fellow at the Lambdalab team at the Politecnico di ...

Scientists in the United Kingdom have developed a new lidar technique that can measure absolute distances with micrometer precision by using a fully electronic system to detect the output from a pair ...

At sunset, this cumulus cloud lit up like a giant jack-o’-lantern in the sky. Rayleigh scattering enriched the horizon with deep reds and oranges, while Mie scattering within the cloud’s droplets ...

The entries—and winners—of our yearly bid for the best optics images ...

Fifty years after their debut, excimer lasers remain vital tools in vision correction, semiconductor lithography and display manufacturing, with fusion research on the horizon. When they were first ...
