In the realm of general relativity, black holes are well-known for their ability to trap light and matter by bending spacetime, creating a point of no return. While black holes have fascinated ...

A new "lensless" device could help, as it uses light to instantly detect harmful microorganisms. Usually, in order to check drinking water for bacteria, a sample of that water must be cultured in a ...

Over the past decades, engineers have introduced numerous technologies that rely on light and its underlying characteristics.

Metasurfaces, ultrathin engineered structures comprised of subwavelength nanoantennas, have emerged as a transformative platform in modern optics. Their ability to manipulate light—controlling phase, ...

Optical logic gates represent a cutting‐edge approach to perform computation entirely with light, bypassing the limitations inherent to electronic components. By exploiting light’s phase, intensity, ...

Kerry Vahala and collaborators from UC Santa Barbara have found a unique solution to an optics problem. When we last checked in with Caltech's Kerry Vahala three years ago, his lab had recently ...

Researchers have developed a new 3D printing method called blurred tomography that can rapidly produce microlenses with commercial-level optical quality. The new method may make it easier and faster ...

Stanford engineers debuted a new framework introducing computational tools and self-reflective AI assistants, potentially ...

On the third floor of the University of Delaware’s Du Pont Hall, electrical engineers analyze delicate, centimeter-sized computer chips on a large optical table surrounded by oscilloscopes, lenses and ...

Setup of the laser speckle contrast optical spectroscopy system used to monitor scalp and brain blood flow during temporary blockage of a major scalp artery near the temple. WASHINGTON, Oct. 21, 2025 ...

A collaborative team has developed a new way to create magnetic optical materials, one that removes a long-standing design ...
