Research & Technology News
Food Waste Transformed into LEDs
SALT LAKE CITY, Oct. 14, 2015 — LEDs made from sugary drinks could reduce waste and replace other light sources made with toxic elements. University of Utah researchers have developed a process for turning food, beverages and even combustion exhaust into light-emitting quantum dots (QDs), which are subsequently integrated into LEDs. The luminescence of carbon dots can be seen when irradiated with UV light. Images courtesy of Prashant Sarswat. Many types of QD are based on rare earth materials, making them
VCSELs Enable Deeper Brain Imaging
SEATTLE, Oct. 14, 2015 — Using light to look more deeply into the living brain could give scientists a better understanding of how dementia, Alzheimer's disease and brain cancer develop over time. Vertical-cavity surface-emitting lasers (VCSELs) are enabling this deeper...
Nano-Engineered Film Has Refractive Index Near 1
RALEIGH, N.C., Oct. 12, 2015 — A dielectric film with a refractive index close to that of air could be used to make photonic devices more efficient and mechanically stable. Photonic devices require high contrast between their component materials, with some components having high...
Design Presents Cheaper Alternative for 2-μm Fiber Lasers
LAUSANNE, Switzerland, Oct. 9, 2015 — A new fiber laser design eliminates a costly component that had been necessary to generate beams around 2 μm, a band useful for surgery, materials processing and atmospheric study. Typical 2-μm lasers are based on an optical fiber ring...
Cloaking Principle Could Boost Solar Cell Performance
KARLSRUHE, Germany, Oct. 6, 2015 — Invisibility cloaking may be a long way from reality, but the principle could help improve the performance of solar cells in the near term. In a series of simulations, researchers at the Karlsruhe Institute of Technology have demonstrated how cloaks...
UV Catheter Plugs Holes in Hearts
BOSTON, Oct. 6, 2015 — With help from UV light, a catheter device could provide a way to repair defects in hearts and other organs without surgery. The device has already been used successfully in animal studies. It was developed jointly by researchers from Boston...
January Start Eyed for National Integrated Photonics Institute
ALBANY, N.Y., Oct. 6, 2015 — Just two months after being selected to create a $610 million national manufacturing institute, a coalition of photonics researchers is aiming for a Jan. 2 launch date. The American Institute for Manufacturing Integrated Photonics — AIM...
Far-Red Stain Safer for Live-Cell Imaging
LAUSANNE, Switzerland, Oct. 2, 2015 — Emitting at the far-red end of the visible light spectrum, a new DNA stain could enable imaging of live cells over the course of a day or more. The stain has three key advantages over existing fluorescent tags used in live-cell imaging, according to...
Fiber Sensors Improve Robot Touch Sensitivity
PITTSBURGH, Sept. 29, 2015 — Fiber optic sensors could give robots the sensitivity needed to handle delicate objects and work safely alongside humans. A newly developed three-fingered soft robotic hand features 14 embedded fiber optic strain sensors that give it the ability to...
'Rectenna' Works at Optical Frequencies
ATLANTA, Sept. 28, 2015 — Made from a forest of modified carbon nanotubes, a "rectenna" has been used for the first time to convert visible light directly into electricity. The device combines the signal-capturing properties of an antenna with those of a rectifier, which...
Broadband Laser Aimed at Cancer Detection
MUNICH, Sept. 25, 2015 — Mid-infrared (MIR) light is rich with molecular "fingerprint" information that can be used to detect anything from atmospheric pollutants to cancer cells. While some lasers already operate in this region, enabling a variety of spectroscopy...
Tissue Scaffolding Made from Laser-Patterned Silk
MEDFORD, Mass., Sept. 24, 2015 — Hydrogels made of silk protein have emerged as a promising platform for tissue engineering thanks to their transparency, which allows laser patterning deep below the material's surface. Silk protein is a soft biomaterial that supports cell growth...
Optical Memory Chip Uses Phase-Change Material
KARLSRUHE, Germany, Sept. 23, 2015 — The first demonstration of a stable nanoscale optical memory chip could allow storage and retrieval of data without the latency inherent in electronic systems. The prototype, developed by researchers in Germany and England, incorporates phase-change...
Detector Seeks Better LED Photometry Results
HELSINKI, Sept. 22, 2015 — A new photometric device could improve the relative uncertainty in measuring the luminous efficacy of LEDs from approximately 5 percent today to 1 percent in the future. Photometers used by lamp manufacturers are largely produced and calibrated with...
3D Data Captured with 2D Camera
DURHAM, N.C., Sept. 18, 2015 — With a few modifications and expanded processing capabilities, standard digital cameras can extract detailed 3D information from a single image. Developed at Duke University, the method does not sacrifice 2D still image quality. Meanwhile, it could...
Laser Ablation Boosts GaAs Terahertz Emission
OKINAWA, Japan, Sept. 18, 2015 — While there is still no cheap and efficient way to mass produce terahertz emitters, laser ablation can increase the output of GaAs, a common semiconductor used in these devices. The surface microstructure of GaAs thin films plays an important role...
Combined Techniques Image Movement of Confined Light
SAN SEBASTIAN, Spain, Sept. 17, 2015 — A combined interferometric and microscopy technique has revealed the strange ways in which light moves when confined inside hyperbolic materials. Researchers at CIC nanoGUNE in the Basque Country and the Institute of Photonic Sciences (ICFO) in...
Metamaterial 'Skin Cloak' Makes Microscale Object Invisible
BERKELEY, Calif., Sept. 17, 2015 — An ultrathin metasurface that has been used to hide microscopic objects could be scaled up to provide visible-light cloaking of macroscale objects, according to its developers at the University of California. The researchers fashioned a "skin cloak"...
Theory Describes 'Molecules' of Light
COLLEGE PARK, Md., Sept. 16, 2015 — New theoretical work shows how two photons can be bound together in much the same way that atoms form molecules. If demonstrated experimentally, the phenomenon could be exploited to enhance photon detectors and enable quantum computing. "Lots of...
Study: Automated Biopsy Assessment Possible with SLIM
CHAMPAIGN, Ill., Sept. 14, 2015 — Spatial light interference microscopy (SLIM) might provide a quantitative way to diagnose breast cancer. Researchers at the University of Illinois recently used data-based SLIM assessment to determine whether breast tissue biopsies from 400 patients...
Light-Sensitive Medium Drives Nanoparticle Assembly
REHOVOT, Israel, Sept. 14, 2015 — Light has long been used to trigger self-assembly of nanoparticles. A new approach may be able to achieve the same end more reliably by focusing light on the medium containing the nanoparticles instead of the nanoparticles themselves. The new...
'Leaky' Antenna Multiplexes THz Signals
PROVIDENCE, R.I., Sept. 14, 2015 — "Leaky" antennas could allow future wireless communications systems operating in the terahertz region to send and receive multiple signals. A prototype developed at Brown University is said to be the first system capable of multiplexing terahertz...
'Nanosprings' Show Promise for Self-Powered Devices
