Capturing light in a waveguide array

Cheaper and more efficient photonic devices, such as lasers, optical fibers, and other light sources may be possible with confined light that is unaffected by imperfections in the material that confines it, according to new ...

How astronomers can leverage fiber nets and listen to deep space

For the first time, researchers have demonstrated that a stable frequency reference can be reliably transmitted more than 300 kilometers over a standard fiber optic telecommunications network and used to synchronize two radio ...

In Appalachia, a public broadband project hits snags

Kentucky's plan to build one of the country's largest publicly owned broadband networks was touted as a cornerstone of the effort to save the Appalachian economy by bringing high-speed internet to some of the poorest counties ...

Technique for making microdroplet lenses

Researchers are on the lookout for rapid, reliable and affordable switches for the opto-electronics of the future. An Empa team now presents a potential solution: dye droplets measuring just a few sub-micrometers in diameter.
