A new angle on controlling light

System could provide first method for filtering light waves based on direction. Light waves can be defined by three fundamental characteristics: their color (or wavelength),...

Unavoidable disorder used to build nanolaser

Researchers the world round are working to develop optical chips, where light can be controlled with nanostructures. These could be used for future circuits...

Crystals ripple in response to light

Light can trigger coordinated, wavelike motions of atoms in atom-thin layers of crystal, scientists have shown. The waves, called phonon polaritons, are far shorter...

3-D images, with only one photon per pixel

Lidar rangefinders, which are common tools in surveying and in autonomous-vehicle control, among other applications, gauge depth by emitting short bursts of laser light...

Accidental discovery dramatically improves conductivity

Quite by accident, Washington State University researchers have achieved a 400-fold increase in the electrical conductivity of a crystal simply by exposing it to...

Bright, laser-based lighting devices

As a modern culture, we crave artificial white lights -- the brighter the better, and ideally using less energy than ever before. To meet...

Bubbles are the new lenses for nanoscale light beams

Bending light beams to your whim sounds like a job for a wizard or an a complex array of bulky mirrors, lenses and prisms,...

Transparent solar film could go on windows, cell phones

Nearly doubling the efficiency of a breakthrough photovoltaic cell they created last year, UCLA researchers have developed a two-layer, see-through solar film that could...

Scientists break record for thinnest light-absorber

Stanford University scientists have created the thinnest, most efficient absorber of visible light on record. The nanosize structure, thousands of times thinner than an...

Almost Perfect: Researcher Nears Creation of Superlens

A superlens would let you see a virus in a drop of blood and open the door to better and cheaper electronics. It might,...
