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

During my first month as a Ph.D. student, a senior student in our group was preparing a presentation for an upcoming Optica meeting. He had led the work from the beginning and knew every detail. Then ...

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 ...

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 ...

Water preferentially attenuates long wavelengths of light, leading to the blue hues familiar to scuba divers. This attenuation means that the undersea environment is not an ideal location for ...

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 ...

Hyperscale cloud providers are driving the demand for high-capacity optical connectivity as they expand their AI and data center infrastructure. In response, optical fiber manufacturer Lightera, USA, ...

Quantum networks that facilitate the transmission of information in the form of qubits are the basis of modern quantum technologies. Photons are used to transfer an excitation from one qubit to ...

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 ...

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 ...

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 ...
