Invisible light beyond the range of human vision plays a vital role in communication technologies, medical diagnostics, and ...

The invention of tiny devices capable of precisely controlling the direction and behavior of light is essential to the development of advanced technologies. Researchers at the Advanced Science ...

Scientists in Switzerland have developed an ultra-thin metalens that converts invisible infrared light into visible light by halving its wavelength, using nanoscale patterns stamped into a special ...

When you unlock a phone, step into view of a security camera or drive past a license plate reader at night, beams of infrared light - invisible to the naked eye — shine onto the unique contours of ...

Researchers have built a paper-thin chip that converts infrared light into visible light and directs it precisely, all without mechanical motion. The design overcomes a long-standing efficiency-versus ...

An inexpensive detector developed by a NASA-led team can now see invisible infrared light in a range of “colors,” or wavelengths. The detector, called a Quantum Well Infrared Photodetector (QWIP) ...

Scientists have developed a new method for detecting mid-infrared (MIR) light at room temperature using quantum systems. Scientists from the University of Birmingham and the University of Cambridge ...

Metasurfaces in which nonlocal light-matter interactions take place are a potentially useful variant of traditional ...

Former Xinjiang government engineer Nureli Abliz, who saw firsthand how surveillance technology flagged thousands of people in China for detention, even when they had committed no crime, is ...
