Spirals of light may lead to better electronics

September 26, 2013 8:10 am | News | Comments

A group of researchers at Caltech has created the optical equivalent of a tuning fork: a device that can help steady the electrical currents needed to power high-end electronics and stabilize the signals of high-quality lasers. The work marks the first time that such a device has been miniaturized to fit on a chip and may pave the way to improvements in high-speed communications, navigation and remote sensing.

Researchers make headway in quantum information transfer

September 24, 2013 8:10 am | News | Comments

Fiber optics has made communication faster than ever, but the next step involves a quantum leap. In order to improve the security of the transfer of information, scientists are working on how to translate electrical quantum states to optical quantum states in a way that would enable ultrafast, quantum-encrypted communications. A research team has demonstrated the first and arguably most challenging step in the process.

Tiny antennas let long light waves see in infrared

September 24, 2013 7:56 am | News | Comments

Univ. of Illinois at Urbana-Champaign researchers have developed arrays of tiny nanoantennas that can enable sensing of molecules that resonate in the infrared (IR) spectrum. Other nanoscale antenna systems can't be tuned to a longer light wavelength due to limitations of traditional nanoantenna materials. The team used highly doped semiconductors, grown by molecular beam epitaxy.


Scientists create twisted light

September 19, 2013 8:50 am | News | Comments

Electronic warfare development targets fully adaptive threat response technology

August 19, 2013 8:17 am | News | Comments

When U.S pilots encounter enemy air defenses, onboard electronic warfare (EW) systems protect them by interfering with incoming radar signals: a technique known as electronic attack (EA) or jamming. Conversely, electronic protection technology prevents hostile forces from using EA methods to disable U.S. radar equipment assets. A research team is now developing a new generation of advanced radio frequency jammer technology.
