Molecular Qualities Captured with Plasmons
MOSCOW, July 9, 2020 — Specific properties of small amounts of molecules can now be isolated with the use of graphene-metal film structures, thanks to the work of scientists in Russia and Spain. Their work focuses on a plasmon, which is an electron oscillation that is coupled with an electromagnetic wave. By focusing these plasmons, they are converted into those with shorter wavelengths, called acoustic plasmons. Probing the vibrational fingerprint of a molecule with a nanofocused acoustic graphene plasmon

Integrated Platform for Visible-Light Chip Could Further Miniaturization
ST. PETERSBURG, Russia, June 26, 2020 — To support the miniaturization of optical devices and components, a scientific team led by researchers at ITMO University has devised a quick, affordable method to make visible-light nanophotonic chips. The light source for the chip can be grown...
Optical Technology Covers Soldiers on Battlefield
IRVINE, Calif., June 26, 2020 — Military personnel have sophisticated technology at their fingertips in combat, and thanks to a federally funded research program, they may soon also have optical technologies ranging from wearable sensors to point-of-care imaging devices to help...
Single-Photon Detectors Could Improve Low-Power OCT Sensitivity
AUCKLAND, New Zealand, June 25, 2020 — A detection technology used in quantum optics also could be used to perform OCT (optical coherence tomography) with lower light power than previously possible, potentially improving the imaging quality available from OCT. “For clinical...
Microlasers Capture Heart’s Rhythm from Inside
ST. ANDREWS, Scotland, June 25, 2020 — Dynamic, rapid changes in the heart that can be seen from the outside are dramatic, but they’re nothing compared to what can be seen inside heart cells themselves. And a research team from the University of St. Andrews has proven exactly that...
Imaging Method Could Detect Liver Disease
BOSTON, June 24, 2020 — It’s currently difficult to screen for certain liver diseases and to monitor these conditions once they’re discovered. A team led by investigators at Massachusetts General Hospital and the Massachusetts Institute of Technology have...
Ultracold Atoms in Optical Traps Could Form Quantum Rings
KRAKOW, Poland, June 23, 2020 — Ultracold atoms trapped in appropriately prepared optical traps can arrange themselves in complex, hitherto unobserved structures, according to scientists from the Institute of Nuclear Physics of the Polish Academy of Sciences (IFJ PAN). In...
