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

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 ...

Researchers have developed a precision magnetometer based on a special material that changes optical properties in response ...

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 chip-scale interface entangles light and electronic states without cryogenic cooling, bringing quantum networking hardware ...

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 ...

Japanese telecom firm NTT and Tokyo-based electronics giant Toshiba are working on new ways around this problem. In November, ...

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 wearable optical device for early detection of hemorrhage during labor or after childbirth. This serious heavy bleeding can be hard to detect before it becomes an ...

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 ...
