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 ...
Metasurfaces, ultrathin engineered structures comprised of subwavelength nanoantennas, have emerged as a transformative platform in modern optics. Their ability to manipulate light—controlling phase, ...
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 ...
All-optical modulation technology is considered an emerging research field that may have a significant impact in the future. As compared to the conventional electrical modulation technology, the most ...
TOKYO--(BUSINESS WIRE)--NTT Corporation (NTT, Head office: Chiyoda-ku Tokyo; President & CEO: Akira Shimada) has developed a digital coherent signal processing circuit and optical device that achieves ...
An Apple optical data transfer patent granted yesterday could facilitate super-fast communications between devices. The patent says that the technology could offer transfer speeds of “terabits per ...
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 ...
Metasurfaces are manipulable artificial materials that can enable lenses to be lowered to one 10,000 th the size of traditional lenses. As a result, metasurfaces have received interest as optical ...
