Theory and practice key to optimized broadband, low-loss optical metamaterials
The union of theory and practice makes broadband, low-loss optical devices practical, which is why two groups of Penn State engineers collaborated to design optical metamaterials that have custom applications ...
Ultra high-speed camera ball-tracker at Japan lab uses mirrors (w/ video)
Transform a ball into a rock -- or make it invisible -- using transformation optics
Fish skin structure explains biological cloaking
The highly effective optical means by which silvery fish, such as the European sardine and Atlantic herring, camouflage themselves from predators is explained this month in Nature Photonics.
Exotic material shows promise as flexible, transparent electrode
(PhysOrg.com) -- An international team of scientists with roots at SLAC and Stanford has shown that ultra-thin sheets of an exotic material remain transparent and highly conductive even after being deeply ...
Scientists use molecular layers to study nanoscale heat transfer
Scientific research has provided us with a fundamental understanding of how light (via photons) and electricity (via electrons) move within and between materials at the micrometer or nanometer levels, making possible a wide ...
Engineers at Yale develop new type of mechanical memory
Physicists create world's smallest semiconductor laser
Physicists at The University of Texas at Austin, in collaboration with colleagues in Taiwan and China, have developed the world's smallest semiconductor laser, a breakthrough for emerging photonic technology ...
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 ...
Bio-inspired coating resists liquids
After a rain, the cupped leaf of a pitcher plant becomes a virtually frictionless surface. Sweet-smelling and elegant, the carnivore attracts ants, spiders, and even little frogs. One by one, they slide to ...
Graphene optical modulators could lead to ultrafast communications
(PhysOrg.com) -- Scientists at the University of California, Berkeley, have demonstrated a new technology for graphene that could break the current speed limits in digital communications.
Boson samplers offering promise for new kinds of computing devices
Flexible silicon solar-cell fabrics may soon become possible
For the first time, a silicon-based optical fiber with solar-cell capabilities has been developed that has been shown to be scalable to many meters in length. The research opens the door to the possibility ...
Data that lives forever is possible: Japan's Hitachi
As Bob Dylan and the Rolling Stones prove, good music lasts a long time; now Japanese hi-tech giant Hitachi says it can last even longer—a few hundred million years at least.
