Optical antenna may allow LEDs to replace lasers in host of devices

By applying 120 year old radio frequency antenna theory to the much newer field of photonics, researchers at Lawrence Berkeley National Laboratory claim to have produced a prototype optical antenna that increases the intensity of emission from a nanorod light source by more than 115 times. This technique may offer the opportunity to replace power-hungry lasers in short-range optical communications devices with enhanced low-power LEDs. Read More

Flexible graphene-based LED clears the way for flexible displays

Researchers from the University of Manchester and University of Sheffield have developed a new prototype semi-transparent, graphene-based LED device that could form the basis of flexible screens for use in the next-generation of mobile phones, tablets and televisions. The incredibly thin display was created using sandwiched "heterostructures", is only 10-40 atoms thick and emits a sheet of light across its entire surface. Read More

NASA unveils countdown clock for the 21st century

It's one of the most famous timepieces in history that's been seen by billions of people all over the world, yet, though it's big, its name isn't Ben. It's the countdown clock at Cape Canaveral, Florida, which has sat in the foreground of historic space mission launches since it was installed in 1969 during the heyday of the Apollo program. But after almost half a century of service, NASA is replacing it with a high-tech LED version that makes its public debut on Thursday during the launch of the Orion EFT-1 mission. Read More
