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 ...
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 ...
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 ...
A tiny device can control laser light very precisely while using much less power, making it possible to build bigger and ...
Metasurfaces, ultrathin engineered structures comprised of subwavelength nanoantennas, have emerged as a transformative platform in modern optics. Their ability to manipulate light—controlling phase, ...
A chip-scale interface entangles light and electronic states without cryogenic cooling, bringing quantum networking hardware ...
