Scientists capture light in a polymeric quasicrystal

ITMO University scientists have conducted several experiments to investigate polymeric quasicrystals that ultimately confirmed their initial theory. In the future, the use of quasicrystals may open up new possibilities for ...

3-D camera earns its stripes

Stripes are in fashion this season at a Rice University lab, where researchers use them to make images that plain cameras could never capture.

Impurities enhance polymer LED efficiencies

Molecular dynamics simulations have shown that the mysteriously high efficiency of polymer LEDs arises from interactions between triplet excitons in their polymer chains, and unpaired electrons in their molecular impurities.

Parylene photonics enable future optical biointerfaces

Carnegie Mellon University's Maysam Chamanzar and his team have invented an optical platform that will likely become the new standard in optical biointerfaces. He's labeled this new field of optical technology "Parylene photonics," ...

Physicists create turnstile for photons

Physicists from Germany, Denmark, and Austria have succeeded in creating a kind of turnstile for light in glass fibers that allows the light particles to only pass through one at a time

Anti-resonant hollow-core optical fiber reduces 'noise'

A new hollow optical fiber greatly reduces the "noise" interfering with the signals it transmits compared to the single-mode fibers now widely used, researchers at the University of Rochester report.

Engineers produce a fisheye lens that's completely flat

To capture panoramic views in a single shot, photographers typically use fisheye lenses—ultra-wide-angle lenses made from multiple pieces of curved glass, which distort incoming light to produce wide, bubble-like images. ...

Resonant tunneling diode oscillators for terahertz-wave detection

A semiconductor device that is promising for both generating and detecting terahertz radiation has been demonstrated by physicists at RIKEN. This may aid the development of high-performance integrated solutions for terahertz ...

Lighting the way to infrared detection

EPFL physicists propose a new path to detect infrared radiation with outstanding sensitivity, allowing detection of signals as low as that of a single quantum of light.

Self-imaging of a molecule by its own electrons

One of the long-standing goals of research on the light-induced dynamics of molecules is to observe time-dependent changes in the structure of molecules, which result from the absorption of light, as directly and unambiguously ...
