(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 ...
What's more interesting than videos of cats chasing laser beams over the kitchen floor? How about videos sent OVER laser beams from NASA's International Space Station back to Earth?
The ability to locate and count small numbers of impurity atoms could lead to advances in modern electronics and optical fiber communication networks.
(Phys.org) —A new laser developed by a research group at Caltech holds the potential to increase by orders of magnitude the rate of data transmission in the optical-fiber network—the backbone of the Internet.
The future of computing may lie not in electrons, but in photons – that is, in microprocessors that use light instead of electrical signals. But these so-called photonic devices are typically built using customized methods ...
(Phys.org) —University of California, San Diego electrical engineering professor Zhaowei Liu and colleagues have taken the first steps in a project to develop fast-blinking LED systems for underwater optical communications.
NASA's Deep Space Network, the world's largest and most powerful communications system for "talking to" spacecraft, will reach a milestone on Dec. 24: the 50th anniversary of its official creation.
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 ...
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.
While the air pressure in a wheel and the blood pressure inside a human body can precisely be measured, it is still a challenge to measure the pressure inside microscopic objects such as cells in our bodies.
