"The new material is roughly ten times thinner than previous radar-absorbing substances, making it viable in fighter jet and ship construction." By Jay Bennett
3-D Molecule Tracking with Nanoscale Accuracy
15 Dec | Optics and Photonics NewsFull Text External Link Indicator
"Researchers led by Nobel Laureate and OSA Fellow W.E. Moerner from Stanford University, USA, report improved accuracy of a single-optical-emitter imaging technique for 3-D tracking of individual molecules (Optica, doi: 10.1364/OPTICA.2.000985). Observing how molecules move and interact with their environment may lead to a better understanding of subcellular biological processes like cell signaling and division." by Sarah Michaud
Scaling Up a Key Single-Photon Source
15 Dec | Optics and Photonics NewsFull Text External Link Indicator
"A major stumbling block to optical quantum information processing (QIP) has been the lack of a good source of single photons—“good,” in this case, defined as a source that pumps out photons both efficiently and deterministically. Scientists in the U.S. and South Korea have now reported significant improvements to one standard technique that can boost single-photon probabilities in narrow time slots nearly sixfold (Optica, doi: 10.1364/OPTICA.2.001010). The team believes that, with some additional development, the technique could enable construction of near-deterministic single-photon sources, clearing a longstanding logjam in scaling up QIP."

Observing Viruses and Nanoparticles with Optical Fiber

"Understanding how viruses assemble inside their hosts may provide valuable information that could help researchers develop new ways to stop viral infections, fabricate novel nanomaterials and deliver genetic material into cells. A research team led by Vinothan Manoharan at Harvard University School of Engineering (HSEAS, USA), reports a new optofluidic fiber platform based on elastic light scattering that can track unlabeled and freely moving individual viruses and nanoparticles with subwavelength precision and microsecond time resolution (ACS Nano, doi: 10.1021/acsnano.5b05646)."

Adaptive Optics Goes Nanoscale
15 Dec | Optics and Photonics NewsFull Text External Link Indicator
"A two-scientist team has devised a method for using the intensity distribution of reflected light to sense and potentially reduce wavefront aberrations at the scale of nanometers (Optica, doi: 10.1364/OPTICA.2.001024). The team believes that the technique—which leverages plasmonics to achieve far denser wavefront sampling than is possible with conventional adaptive-optics (AO) techniques—could find use not only in typical AO settings but also in metrology, chemical sensing and other areas." by Stewart Wills
Nanopillars Hide Solar Wiring

"Photovoltaics convert the photons from light into a voltage—thus the name. And anything that reduces the number of photons that strike the electric field of the semiconducting P-N junction inside the solar cell will reduce the voltage it generates." By Dexter Johnson
Researchers create a near-perfect sound absorbing system

"We've come a long way since the days of pouring wax into our ears to block out siren songs. A team of researchers at Hong Kong University of Science and Technology have developed a sound-cancelling system that eliminates 99.7 percent of noise, no matter how quiet."

Near-Perfect Absorbers That Are Tunable, Flexible—and Cheap
22 Nov | Optics & Photonics NewsFull Text External Link Indicator
"Spectrally selective light absorbers are used in a wide range of advanced photonic applications—but producing large-area metasurfaces for near-perfect absorption has been an expensive proposition. A team of scientists from Duke University, USA, has now reportedly come up with a simple, scalable chemical technique for creating such metasurfaces, using deposition of silver nanocubes atop a layered metal-polymer foundation (Adv. Mater., doi: 10.1002/adma.201503281). The result, according to the team, is “truly macroscopic,” near-perfect-absorption metasurfaces that are tunable from the visible to the near-infrared—and that could find application in photodetectors, imaging sensors and other devices." by Stewart Wills
