Controlling light on a chip at the single-photon level

Integrating optics and electronics into systems such as fiber-optic data links has revolutionized how we transmit information. A second revolution awaits as researchers seek to develop chips in which individual atoms control ...

Bending the light with a tiny chip

(Phys.org) —Imagine that you are in a meeting with coworkers or at a gathering of friends. You pull out your cell phone to show a presentation or a video on YouTube. But you don't use the tiny screen; your phone projects ...

Laser light at useful wavelengths from semiconductor nanowires

Thread-like semiconductor structures called nanowires, so thin that they are effectively one-dimensional, show potential as lasers for applications in computing, communications, and sensing. Scientists at the Technische Universitaet ...

Guyana and Suriname lose Internet, overseas calls

The Guyana Telephone and Telegraph Co. says damage to an undersea fiber-optic cable has caused a phone and Internet outage that affected much of the country along with neighboring Suriname.

NSA collected thousands of US communications (Update 2)

The National Security Agency declassified three secret court opinions Wednesday showing how in one of its surveillance programs it scooped up as many as 56,000 emails and other communications by Americans not connected to ...

Research promises breakthrough in internet bandwidth (w/ Video)

As rapidly increasing demand for bandwidth strains the Internet's capacity, a team of engineers has devised a new fiber optic technology that promises to increase bandwidth dramatically. The new technology could enable Internet ...

Data highway for quantum information

Researchers at the Vienna University of Technology quantum mechanically couple atoms to glass fiber cables. Now, they have shown that their technique enables storage of quantum information over a sufficiently long period ...
