Study finds single photons cannot exceed the speed of light
Generating Mobius strips of light: Researchers experimentally produce these structures from light polarization
A collaboration of researchers from Canada, Europe and the USA have experimentally produced Möbius strips from the polarization of light, confirming a theoretical prediction that it is possible for light's ...
255 Terabits/s: Researchers demonstrate record data transmission over new type of fiber
Researchers at Eindhoven University of Technology (TU/e) in the Netherlands and the University of Central Florida (CREOL), report in the journal Nature Photonics the successful transmission of a record high 2 ...
Three-dimensional opto-electric integration
Three-dimensional (3D) integration of various materials on top of bulk silicon could be the best answer for cost-effectively marrying optical devices with electronics. A*STAR researchers have used this approach ...
Researchers use sound to slow down, speed up, and block light
How do you make an optical fiber transmit light only one way? Researchers from the University of Illinois at Urbana-Champaign have experimentally demonstrated, for the first time, the phenomenon of Brillouin ...
Researchers build reversible tractor beam that moves objects 100 times farther than other efforts
Proposal for optical transistor uses light to control light
Entanglement on a chip: Breakthrough promises secure communications and faster computers
Unlike Bilbo's magic ring, which entangles human hearts, engineers have created a new micro-ring that entangles individual particles of light, an important first step in a whole host of new technologies.
Physicists show that superfluid light is possible
Turning loss to gain: Cutting power could dramatically boost laser output
Lasers – devices that deliver beams of highly organized light – are so deeply integrated into modern technology that their basic operations would seem well understood. CD players, medical diagnostics ...
Vertical cavity quantum switch could lead us away from electronics-based computing
Through a Sensor, Holographically
New material gives visible light an infinite wavelength
Researchers from the FOM Institute AMOLF and the University of Pennsylvania have fabricated a material which gives visible light a nearly infinite wavelength. The new metamaterial is made by stacking silver ...
Do-it-yourself invisibility with 3-D printing
Seven years ago, Duke University engineers demonstrated the first working invisibility cloak in complex laboratory experiments. Now it appears creating a simple cloak has become a lot simpler.
