In space, does light travel forever or fade as the universe expands?
Light released by a distant star does not simply wink out after crossing some threshold of space. In a vacuum, photons keep moving indefinitely, and astronomers routinely detect light that has ...
Optical frequency combs—laser sources that emit evenly spaced colors of light—are foundational, ubiquitous tools for precision measurement, found in optical clocks, gas-sensing spectrometers, and ...
Researchers aim to develop new quantum light sources and technology for scalable quantum networks based on the rare-earth element erbium. (Nanowerk News) Quantum technology enables unbreakable ...
A tiny metasurface chip can turn invisible infrared light into steerable visible beams, opening the door to powerful new ...
Chinese scientists are harnessing the capabilities of the science satellite SDGSAT-1 to tackle the growing issue of light pollution in urban settings. A recent study by the Aerospace Information ...
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 ...
