Invisibility carpet cloak can hide objects from visible light
Scientists examine possibility of a phonon laser, or 'phaser'
Fiber-wireless (Fi-Wi) to provide ultra-high-speed, short-range communication
Using lasers to cool and manipulate molecules
Engineers break power and distance barriers for fiber optic communication
Electrical engineers have broken key barriers that limit the distance information can travel in fiber optic cables and still be accurately deciphered by a receiver. Photonics researchers at the University ...
Engineers efficiently 'mix' light at the nanoscale
The race to make computer components smaller and faster and use less power is pushing the limits of the properties of electrons in a material. Photonic systems could eventually replace electronic ones, but ...
Spirals of light may lead to better electronics
(Phys.org) —A group of researchers at the California Institute of Technology (Caltech) has created the optical equivalent of a tuning fork—a device that can help steady the electrical currents needed ...
Researchers discover way to allow 80 percent of sound to pass through walls
Researchers suggest magicians' mirror tricks could be used as large scale cloaking devices (w/ video)
Do-it-yourself invisibility with 3-D printing
Seven years ago, Duke University engineers demonstrated the first working invisibility cloak in complex laboratory experiments. Now it appears creating a simple cloak has become a lot simpler.
Researchers create design for nanometer-scale material that can speed up, squeeze light
(Phys.org) —In a process one researcher compares to squeezing an elephant through a pinhole, researchers at Missouri University of Science and Technology have designed a way to engineer atoms capable of ...
Quantum kisses change the color of nothing
Even empty gaps have a colour. Now scientists have shown that quantum jumps of electrons can change the colour of gaps between nano-sized balls of gold. The new results, published today in the journal Nature, set a ...
The world's most stable laser also promises heightened test precision
(Phys.org)—The world's most stable laser – with frequency variation of no more than 2 parts in 10,000 trillion – has been developed and tested by an international collaboration of scientists at NIST/JILA ...
