New Way to Lock Structural Color

Iridescence, or sheen that shifts color depending on your viewing angle, is pretty in peacock feathers. But it's been a nuisance for engineers trying to mimic the birds' unique color mechanism to make high-resolution, reflective, color display screens.

Twisted Light Wave May Add Capacity to Future Optical Communications Networks

At a time when communication networks are scrambling for ways to transmit more data over limited bandwidth, a type of twisted light wave is gaining new attention. Called an optical vortex or vortex beam, this complex beam resembles a corkscrew, with waves that rotate as they travel.

Nanomechanical Dual-Core Optical Fibers Enhance Data Processing

Optical fibers –the backbone of the Internet–carry movies, messages, and music at the speed of light. But for all their efficiency, these ultrathin strands of pristine glass must connect to sluggish signal switches, routers, and buffers in order to transmit data. Hoping to do away with these information speed bumps, researchers have developed a new, dual-core optical fiber that can perform the same functions just by applying a miniscule amount of mechanical pressure.

Novel Device Focuses Light to a Point at the Nanoscale

As technology advances, it tends to shrink. From cell phones to laptops—powered by increasingly faster and tinier processors—everything is getting thinner and sleeker. And now light beams are getting smaller, too.

New Method to Produce Metal-Organic Frameworks for Optics, Photonics Applications

Researchers of the KIT Institute of Functional Interfaces (IFG), Jacobs University Bremen, and other institutions have developed a new method to produce metal-organic frameworks (MOFs). By means of the so-called liquid-phase epitaxy, the scientists succeeded in producing a new class of MOFs with a pore size never reached before. These frameworks open up interesting applications in medicine, optics, and photonics. The new class of MOFs, called "SURMOF 2", is presented in the "Nature Scientific Reports" journal.

New Artificial Lens Nearly Identical to Human Eye Lens

Drawing heavily upon nature for inspiration, a team of researchers has created a new artificial lens that is nearly identical to the natural lens of the human eye. This innovative lens, which is made up of thousands of nanoscale polymer layers, may one day provide a more natural performance in implantable lenses to replace damaged or diseased human eye lenses, as well as consumer vision products; it also may lead to superior ground and aerial surveillance technology.
