From PhysOrg.com:
Berkeley Lab researchers have found a new mechanism by which the photovoltaic effect can take place in semiconductor thin-films. This new path to energy production brightens the future for photovoltaic technology by overcoming voltage limitations that plague conventional solid-state solar cells.Full article
From Science:
A tiny ladderlike beam of silicon converts light into vibrations and vice versa with extremely high efficiency, physicists report. That may seem like an esoteric result, but the finding could open the way to new physics and someday serve as a key element in optical microcircuits akin to the electronic microcircuits in computer chips.Full article
From PhysOrg.com:
For the first time, physicists have demonstrated the quantum entanglement of three light beams, all of different wavelengths. Entanglement of two light beams of different wavelengths has already been demonstrated, but the researchers explain that going beyond two beams is important since three beams can serve as connections at the nodes of a quantum network.Full article
From PhysOrg.com:
Researchers have created the tiniest laser since its invention nearly 50 years ago...Full article
Nanophotonics may usher in a host of radical advances, including powerful "hyperlenses" resulting in sensors and microscopes 10 times more powerful than today's and able to see objects as small as DNA; computers and consumer electronics that use light instead of electronic signals to process information; and more efficient solar collectors.
'The photon force is with us': Harnessing light to drive nanomachines from PhysOrg.com
Science fiction writers have long envisioned sailing a spacecraft by the optical force of the sun's light. But, the forces of sunlight are too weak to fill even the oversized sails that have been tried. Now a team led by researchers at the Yale School of Engineering & Applied Science has shown that the force of light indeed can be harnessed to drive machines — when the process is scaled to nano-proportions.

A step toward circuits for terahertz computing from PhysOrg.com
University of Utah engineers took an early step toward building superfast computers that run on far-infrared light instead of electricity: They made the equivalent of wires that carried and bent this form of light, also known as terahertz radiation, which is the last unexploited portion of the electromagnetic spectrum.

Nanophotonic switch device for routing light on a chip scale from PhysOrg.com
IBM scientists today took another significant advance towards sending information inside a computer chip by using light pulses instead of electrons by building the world’s tiniest nanophotonic switch with a footprint about 100X smaller than the cross section of a human hair.

IBM using light instead of wires for building supercomputers-on-a-chip from PhysOrg.com
Supercomputers that consist of thousands of individual processor "brains" connected by miles of copper wires could one day fit into a laptop PC, thanks in part to a breakthrough by IBM scientists announced today.
