Using their Mosquito fabrication method, the researchers created a fan-out pattern of multiple thin light paths inside a thin sheet of PDMS. This created four optical channels that could be used for ...

A dust sensor is an optical electronic system to detect fine particles such as dust. In principle, an optical dust sensor detects the dust particle concentration the in air by using an optical sensing ...

Researchers have developed a new optical sensor that provides a simple way to achieve real-time detection of extremely low levels of arsenic in water. Researchers have developed a new optical sensor ...

New research has shown how the quantum mechanical principle of strong coupling opens unrivalled possibilities for designing optical filters. A team of researchers from the University of Cologne, ...

Twisted moiré photonic crystals—an advanced type of optical metamaterial—have shown enormous potential in the race to engineer smaller, more capable and more powerful optical systems. How do they work ...

(Nanowerk Spotlight) In the age of big data, we are generating more images than we can actually process. Autonomous vehicles, medical scanners, and quality control systems rely heavily on ...
