New spectroscopy method could lead to better optical devices
A multi-university research team has used a new spectroscopic method to gain a key insight into how light is emitted from layered nanomaterials and other thin films.
Flexible design approach for nanosensors that overcomes practicality and reliability issues now available
(Phys.org)—Metal nanostructures can act as tiny antennae to control light since they can focus and guide light on the smallest of scales. The optical properties of these antennae depend strongly on their ...
Metamaterials provide active control of 'slow light' devices
LANL researchers and collaborators have made the first demonstration of rapidly switching on and off "slow light" in specially designed metamaterials at room temperature. Metamaterials are assemblies of ...
Researchers build SQUID device that demonstrates the Josephson effect
New device hides, on cue, from infrared cameras: Tunable material boasts nearly 100 percent absorption
Now you see it, now you don't. A new device invented at the Harvard School of Engineering and Applied Sciences (SEAS) can absorb 99.75% of infrared light that shines on it. When activated, it appears black ...
Researchers spray-paint ultrathin coatings that change color with only a few atoms' difference in thickness
In Harvard's Pierce Hall, the surface of a small germanium-coated gold sheet shines vividly in crimson. A centimeter to the right, where the same metallic coating is literally only about 20 atoms thicker, ...
Electronics play by a new set of rules at the molecular scale
(Phys.org)—In a paper published in Nature Nanontechnology on September 2, 2012, scientists from the DOE's Brookhaven National Laboratory and Columbia University's departments of Chemistry and of Applie ...
Physicists demonstrate quantum interference between two photons of different frequencies
U of Toronto experiment named top breakthrough of 2011 by Physics World
Aephraim Steinberg and colleagues at the Centre for Quantum Information and Quantum Control at the University of Toronto had the top physics breakthrough of the year according to Physics World magazine.
Researchers create light from 'almost nothing'
Quantum physics first: Researchers observe single photons in two-slit interferometer experiment
Quantum mechanics is famous for saying that a tree falling in a forest when there's no one there doesn't make a sound. Quantum mechanics also says that if anyone is listening, it interferes with and changes the tree. And ...
