Physicists have developed a spectral-filtering technique that strips away unwanted extra photons from quantum light sources, ...

A chip‑scale laser array with integrated beam shaping enables ultrafast, energy‑efficient optical wireless links for indoor ...

This study proposes a novel method to accurately estimate modulation amplitude and determine spatial resolution in BOCDR without additional devices. Brillouin scattering is the phenomenon of the ...

Most laser sources produce Gaussian beams that diverge as they propagate. This natural spreading limits their effectiveness in applications that require light to remain concentrated over long ...

Large-aperture interferometers are important in the manufacturing and measurement of large-aperture optical elements, which play critical roles in the fields of optical precision manufacturing and ...

Researchers cracked the mystery of altermagnets, materials with no net magnetization yet strange light-reflecting powers, by creating a new optical measurement method. Their findings confirmed ...

Artificial intelligence grows more demanding every year. Modern models learn and operate by pushing huge volumes of data through repeated matrix operations that sit at the heart of every neural ...

Transferring optical information in free space with large bandwidth and high transmission capacity has gained significant attention in various applications, such as remote sensing, underwater ...

CU Boulder postdoc Catherine Saladrigas is helping bring high-resolution imaging into miniature microscopes for neuroscience research. In a promising leap forward for imaging, Saladrigas and a team of ...

The effects of humidity are evident in the stability and shelf-life of a variety of materials, formulations, and processing behaviour, especially food materials. This article discusses the advantages ...
