Laser frequency combs may be the future of Wi-Fi

Wi-Fi and cellular data traffic are increasing exponentially but, unless the capacity of wireless links can be increased, all that traffic is bound to lead to unacceptable bottlenecks.

Using sound waves to image nanostructures

The potential of an ultrafast form of transmission electron microscopy to measure sound waves in nanostructures has been demonstrated by three RIKEN physicists. This could help realize a high-resolution imaging method that ...

'Star Comb' joins quest for Earthlike planets

(PhysOrg.com) -- If there is life on other planets, a laser frequency comb developed at the National Institute of Standards and Technology (NIST) may help find it.

New sensor exploits traditional weakness of nano devices

By taking advantage of a phenomenon that until now has been a virtual showstopper for electronics designers, a team led by Oak Ridge National Laboratory's Panos Datskos is developing a chemical and biological sensor with ...

Using noise to enhance optical sensing

In conventional sensing methods, noise is always a problem, especially in systems that are meant to detect changes in their environment that are hardly bigger or even smaller than the noise in the system. Encountering this ...

One laser is enough

Gases in the environment can be spectroscopically probed fast and precisely using so-called dual frequency combs. Researchers at ETH have now developed a method by which such frequency combs can be created much more simply ...
