Japanese universities develop new world's fastest camera
No need for color correction: Perfect colors, captured with one ultra-thin lens
Most lenses are, by definition, curved. After all, they are named for their resemblance to lentils, and a glass lens made flat is just a window with no special powers. But a new type of lens created at the ...
Helicopter-light-beams: A new tool for quantum optics
A light wave oscillates perpendicular to its propagation direction – that is what students learn in school. However, scientists of the Vienna University of Technology (TU Vienna) now perform atom-physics ...
IBM Scientists Create Ultra-Fast Device Which Uses Light for Communication between Computer Chips
(PhysOrg.com) -- IBM scientists today unveiled a significant step towards replacing electrical signals that communicate via copper wires between computer chips with tiny silicon circuits that communicate using ...
Closing in on Einstein's window to the universe
(Phys.org) —Nearly a century after the world's greatest physicist, Albert Einstein, first predicted the existence of gravitational waves, a global network of gravitational wave observatories has moved a ...
Novel negative-index metamaterial that responds to visible light designed
A group of scientists led by researchers from the California Institute of Technology has engineered a type of artificial optical material—a metamaterial—with a particular three-dimensional structure such ...
Interplanetary precision laser could reach to Mars and beyond
Entanglement on a chip: Breakthrough promises secure communications and faster computers
Unlike Bilbo's magic ring, which entangles human hearts, engineers have created a new micro-ring that entangles individual particles of light, an important first step in a whole host of new technologies.
Engineers make sound loud enough to bend light on a computer chip
During a thunderstorm, we all know that it is common to hear thunder after we see the lightning. That's because sound travels much slower (768 miles per hour) than light (670,000,000 miles per hour).
A Polymer Solar Cell with Near-Perfect Internal Efficiency
Regular Light Bulbs Made Super-Efficient with Ultra-Fast Laser
(PhysOrg.com) -- An ultra-powerful laser can turn regular incandescent light bulbs into power-sippers, say optics researchers at the University of Rochester. The process could make a light as bright as a 100-watt ...
Researchers fabricate first large-area, full-color quantum dot display
Novel X-ray device developed
Using a compact but powerful laser, a research team at the University of Nebraska-Lincoln has developed a new way to generate synchrotron X-rays.
Smaller, cheaper, 300 times more intense: Scientists prove theory which could revolutionise lasers
(PhysOrg.com) -- More brilliant X-rays, more cost-effective methods for developing new energy sources and advanced manufacturing processes are just some of the benefits which may come from a novel technology, ...
