Building a bridge to the quantum world

Entanglement is one of the main principles of quantum mechanics. Physicists from Professor Johannes Fink's research group at the Institute of Science and Technology Austria (IST Austria) have found a way to use a mechanical ...

Microscopic glass blowing used to make tiny optical lenses

Inserting air into hot glass to form a bubble has been used to make glass objects since Roman times. In new work, researchers apply these same glass blowing principles on a microscopic scale to make specialized miniature ...

Laser method promising for detecting trace chemicals in air

Researchers have developed a new laser-based method that can detect electric charges and chemicals of interest with unprecedented sensitivity. The new approach could one day offer a way to scan large areas for radioactive ...

Researchers improve semiconductor laser on silicon

Electrical engineering researchers have boosted the operating temperature of a promising new semiconductor laser on silicon substrate, moving it one step closer to possible commercial application.
