Researchers make first perovskite-based superlens for the infrared
Superlenses earned their superlative by being able to capture the "evanescent" light waves that blossom close to an illuminated surface and never travel far enough to be "seen" by a conventional lens. Superlenses ...
New laser technology prepares to revolutionize communications
As fiber optic technology continues to advance, it faces challenges from both its physical properties and its use of infrastructure. One emerging high-speed solution being developed at Stevens Institute of Technology uses ...
New lens doubles the resolution of conventional microscopes
Breakthrough in ultra-sensitive sensor technology
Princeton researchers have invented an extremely sensitive sensor that opens up new ways to detect a wide range of substances, from tell-tale signs of cancer to hidden explosives.
Trapping a rainbow: Researchers slow broadband light waves with nanoplasmonic structures
A team of electrical engineers and chemists at Lehigh University have experimentally verified the "rainbow" trapping effect, demonstrating that plasmonic structures can slow down light waves over a broad range of wavelengths.
Scientists reverse Doppler Effect
(PhysOrg.com) -- Researchers from Swinburne University and the University of Shanghai for Science and Technology have for the first time ever demonstrated a reversal of the optical Doppler Effect ...
Researchers fabricate first large-area, full-color quantum dot display
A guide star lets scientists see deep into human tissue
Astronomers have a neat trick they sometimes use to compensate for the turbulence of the atmosphere that blurs images made by ground-based telescopes. They create an artificial star called a guide star and ...
Engineers grow nanolasers on silicon, pave way for on-chip photonics
Engineers at the University of California, Berkeley, have found a way to grow nanolasers directly onto a silicon surface, an achievement that could lead to a new class of faster, more efficient microprocessors, ...
Researchers demonstrate highly unidirectional 'whispering gallery' microlasers
Utilizing a century-old phenomenon discovered in St. Paul's Cathedral, London, applied scientists at Harvard University have demonstrated, for the first time, highly collimated unidirectional microlasers.
Optical lifting demonstrated for the first time (w/ Video)
'Space-time cloak' to conceal events revealed in new study
(PhysOrg.com) -- The study, by researchers from Imperial College London, involves a new class of materials called metamaterials, which can be artificially engineered to distort light or sound waves. With conventional ...
Moving holograms: From science fiction to reality (w/ Video)
Remember the Star Wars scene in which R2D2 projects a three-dimensional image of a troubled Princess Leia delivering a call for help to Luke Skywalker and his allies? What used to be science fiction is now ...
Light on silicon better than copper?
Step aside copper and make way for a better carrier of information -- light.
