New Fabrication Platform Brings Photonics to Bulk Silicon Microelectronic Chips
BROOKLINE, Mass., April 26, 2018 — A microchip technology that is capable of optically transferring data could alleviate bottlenecks in current devices by speeding data transfer and reducing energy consumption by orders of magnitude. The new method that has been developed for fabricating silicon chips that can communicate with photons is no more expensive than current chip technology. Most silicon nanotechnologies rely on bulk silicon substrates, which are limited in their ability to integrate with photonic functions. The
Squeezed Light Confined to Space of One Atom in Nanophotonics Advance
BARCELONA, Spain, April 25, 2018 — Using graphene, researchers have found a way to confine light down to a space that is one atom thick. The ability to confine light to such a small space could pave the way for ultrasmall optoelectronic devices. Previous work has shown that while...
Hidden In The Shadows No More
Apr 24, 2018 — Thermal cameras are actively deployed on aerial and ground vehicles, in watchtowers, and at checkpoints for surveillance purposes. More recently, thermal cameras are becoming available for use as body-worn cameras. Researchers at the U.S. Army...
UV Light Exposure Causes Composite Material to Grow Stronger On Demand
ABERDEEN PROVING GROUND, Md., April 24, 2018 — A technique has been developed that causes a composite material to become stiffer and stronger when exposed to UV light. The technique can be controlled, allowing the strength of the material to be adapted to the requirements of the application. To...
AO-LLSM Microscope Achieves Aberration-Free Imaging
ASHBURN, Va., April 23, 2018 — Scientists have combined lattice light-sheet microscopy (LLSM) with adaptive optics (AO) to capture high-resolution 3D movies of cells deep within living systems. The AO-LLSM microscope enables cells to be viewed in their native multicellular...
Short, Strong Laser Pulses Advance Understanding of Strongly Correlated Materials
BERLIN, Germany, April 20, 2018 — In its search for materials and technologies that could help push the speed and storage limits of silicon-based computer technology, a team of researchers looked at a category of materials known as “strongly correlated systems,” so called because of...
Seaweed Forms Dynamic Opal-Like Photonic Nanostructures
BRISTOL, England, April 20, 2018 — Intracellular opal-like photonic crystals, formed from lipids within photosynthetic cells, have been observed to produce vivid structural color in the algae Cystoseira tamariscifolia. The bright blue and green iridescent sheen from the brown algae...
Whispering Gallery for Light Boosts Solar Cell Absorption and Photocurrent
GAITHERSBURG, Md., April 18, 2018 — Researchers have developed a nanoscale coating for solar cells that enables the cells to absorb about 20 percent more sunlight than uncoated devices. The coating, developed by trapping light using an optical version of a whispering gallery, could...
New Bose-Einstein Condensate Couples Light with Metal Electrons
ESPOO, Finland, April 18, 2018 — Researchers created a new Bose-Einstein condensate, where the condensed particles were mixtures of light and metal electrons (so-called surface plasmon polaritons), in motion in gold nanorods arranged into a periodic array. Unlike most previous...
New Book Addresses Issues, Offers Solutions for LOS Control
PITTSFIELD, Mass., April 17, 2018 — In Stabilizing the Line of Sight, authors Peter J. Kennedy and Rhonda L. Kennedy provide a methodology and an example for executing a successful end-to-end LOS design. Comprehensive in scope, this book will give readers a better understanding of the...
Researchers Attain Largest Entangled Quantum Register to Date
INNSBRUCK, Austria, April 16, 2018 — A research team at the Institute of Quantum Optics and Quantum Information (IQOQI) in Innsbruck, together with researchers from the University of Ulm and the Institute of Quantum Optics and Quantum Information (Vienna), has achieved controlled...
Optofluidic Smart Glass System Is Cost-Efficient, High Performing
NEWARK, Del., April 16, 2018 — Smart glass panels that can switch between allowing light in and blocking it out could one day be used in eco-friendly windows, windshields, roof panes and building envelopes to absorb light and heat in cold weather and reflect heat away from...
Tiny Fiber Optic Probe Senses Body Temps, Performs OCT Imaging
ADELAIDE, Australia, April 16, 2018 — A miniaturized fiber optic probe has been invented that can simultaneously measure body temperature and take images deep inside the body. The single-fiber-based image and sensing probe uses an OCT lens fabricated at the distal end of a double-clad...
Plant Protein Powers Red Light-Activated Switch for Animal Cells
LA JOLLA, Calif., April 11, 2018 — An optogenetic switch activated by red and far-red light has been designed and tested in animal cells. The light-activated switch, which does not require the addition of sensing molecules from outside the cells, could be used to turn genes on and...
Technique to Suppress Photobleaching Increases Imaging Window
OKINAWA, Japan, April 10, 2018 — To better understand how proteins move and interact within the cell membrane, an imaging method called live-cell single fluorescent-molecule imaging (SFMI) can be used to tag each protein in the membrane individually with fluorescent markers. The...
Van Gils Appointed as VTT Research Professor
ESPOO, Finland, April 10, 2018 — VTT Technical Research Centre of Finland has appointed Mark van Gils as research professor in charge of artificial intelligence in wellness and health care. Van Gils has previously worked as a principal scientist at VTT and is also a docent at Aalto...
Gaining Nanoscale Control over Quantum Systems
OAK RIDGE, Tenn., April 9, 2018 — Scientists at Oak Ridge National Laboratory (ORNL) and Vanderbilt University have developed methods to help control the “leaky,” dissipative behavior inherent in quantum systems and materials. To do so, they examined the quantum nature...
Microsensor Could Help Individualize Dialysis Treatment
EINDHOVEN, Netherlands, April 9, 2018 — A new microsensor could make it possible to directly monitor and adjust the composition of kidney dialysis fluid (dialysate) — an important step toward customizing dialysis to the individual patient. The sensor provides a way to monitor the...
Optically Heated Nanotweezers Manipulate Materials at Nanoscale
AUSTIN, Texas, April 9, 2018 — Opto-thermoelectric nanotweezers (OTENTs) have been developed that use light at the nanoscale to manipulate metal nanoparticles in a wide range of materials, sizes, and shapes, with single-particle resolution. OTENTs could open new possibilities for...
Massive Hologram Conveys Jet Engine in Golden Hues
Apr 4, 2018 — Today, most of us need not look very far to see a hologram. They’re a common anticounterfeit feature on driver’s licenses and credit cards. But they weren’t always so commonplace — or small, for that matter. Case in point:...
Cosmic Lens Helps Hubble Capture Image of Most Distant Star Ever Seen
BERKELEY, Calif., April 3, 2018 — Gravitational lensing — the bending of light by massive galaxy clusters in the line of sight — has occurred during a rare cosmic alignment, magnifying a star more than 2,000 times. The phenomenon allowed astronomers to capture an image...
