Data For The Masses
Mar 26, 2015 — Hindsight is 20/20. In February of 1995, Newsweek published an article titled “The Internet? Bah!” wherein the author deemed the hype surrounding an online future to be a large helping of “baloney.” Twenty years later, fiber optic cables buried in the ocean floor carry over 99 percent of that so-called drivel to millions of people – who rely upon the data like never before. Currently, 299 cable systems are active, under construction or expected to be fully funded
Nanolaser Uses Atomically Thin Gain Medium
SEATTLE, March 26, 2015 — With potential for on-chip optical communications applications, a tungsten-based nanoscale laser operates reliably on a tiny amount of electricity. Developed by researchers at Washington and Stanford universities, the device incorporates a photonic...
Photonics Advances in the ‘Land of Ideas’
Mar 26, 2015 — The Abbe refractometer. The stauroscope. The Easter Bunny, the modern tradition of Christmas trees, and the accordion. All of these originated in Germany, and each has made a significant impact on the world. And the country’s innovative spirit...
Natcore, Eurotron Partner on HIT Solar Cells
RED BANK, N.J., March 24, 2015 — Natcore Technology Inc. has teamed up with Eurotron B.V. to produce next-generation photovoltaic modules. The company recently announced that it had produced an all-back-contact silicon heterojunction with intrinsic thin layer (HIT) solar cell using...
Pairing of Silicon, Perovskite Promising for Solar Efficiency
CAMBRIDGE, Mass., March 24, 2015 — A pairing of silicon and perovskite has the potential to achieve significantly higher solar energy conversion efficiencies than standard, single-junction silicon cells. A prototype tandem solar cell developed by researchers at MIT and Stanford...
Squid Skin Inspires IR Camouflage Tape (with video)
IRVINE, Calif., March 24, 2015 — A protein derived from squid skin could be adapted into a kind of IR camouflage for soldiers. Researchers from the University of California, Irvine, have developed an adhesive film that, when stretched, reflects near-infrared light. Future versions...
Honeycomb Steers Light around Sharp Curves
ORLANDO, Fla., March 20, 2015 — Microscale plastic honeycomb structures can make light beams turn on a dime, a development that could allow more optical relays to be packed onto photonic integrated chips. These spatially variant photonic crystals (SVPCs) were designed by...
Quantum Materials Breaks ‘Stokes Shift Barrier’ for QD Clarity
SAN MARCOS, Texas, March 18, 2015 — Quantum Materials Corp. said it has found the secret for mass producing clearer, brighter quantum dots (QDs) for displays and other applications. The company said a patented, continuous-flow process allows consistent, high-volume production of QDs...
Melody Encoded onto Plasmonic Nanostructure
CHAMPAIGN, Ill., March 17, 2015 — With data storage capacity 5600 times greater than magnetic film, a chip made of tiny gold bow ties could be the next best place to store all your MP3s. Researchers from the University of Illinois at Urbana-Champaign recently created the first-ever...
Photoelectric Dye May Restore Some Sight to the Blind
OKAYAMA, Japan, March 13, 2015 — Photoelectric dyes may be used to send images to the brains of the blind, potentially presenting a simpler alternative to artificial eyes based on image sensors. Blind patients with hereditary diseases such as retinitis pigmentosa have dead...
Narrower Lasers Could Yield Better Atomic Clocks
COPENHAGEN, Denmark, March 10, 2015 — Atomic clocks lose 1 second every 300 million years, but that level of accuracy isn’t good enough for researchers at the Niels Bohr Institute. For even better precision, they’ve devised a new way to narrow the linewidth of the red lasers...
Nanowire Optical Properties Tuned by Alloy Catalyst
BERKELEY, Calif., March 9, 2015 — A new growth catalyst gives greater control over the colors of light emitted by gallium nitride nanowires. Rather than using a single metal, researchers at Lawrence Berkeley National Laboratory used gold-nickel alloys as a catalyst. By altering the...
Black Phosphorus Shows Promise in Optical Circuits
MINNEAPOLIS, March 5, 2015 — With a tunable bandgap, black phosphorus could be used to make better optical communications circuits than graphene and even germanium. Researchers at the University of Minnesota used black phosphorus, a 2-D, stable crystalline form of phosphorus,...
Semrock Names Life Sciences Catalog Leader
ROCHESTER, N.Y., Feb. 25, 2015 — Semrock has named Dr. Prashant Prabhat the new business line leader for its newly formed life sciences catalog business segment. Prabhat and his team will focus on growing the catalog filter business, which supports researchers in fluorescence...
Multilayer QD Solar Cells Promising for Natcore
RED BANK, N.J., Feb. 23, 2015 — A new breed of quantum dots (QDs) could enable multilayer solar cells that capture more of the sun’s energy. Natcore Technology Inc. said scientists in the laboratories of co-founder Dr. Andrew Barron, who is also a professor at Rice...
Asia-Pacific: Manufacturing the Future
Feb 13, 2015 — The world of laser-based 3-D printing is one of endless possibilities, so much so that trying to predict its advances seems pointless. Since its emergence in the 1980s, laser-based additive manufacturing has evolved into many forms, including...
LSCM and RelA for Quantifying Microwear: A Case Study
Feb 13, 2015 — Laser scanning confocal microscopy and relative area are effective tools for surface-roughness analysis of experimental Mistassini quartzite scrapers. Laser scanning confocal microscopy (LSCM) and relative area (RelA) are effective tools for the...
Nanoimprint Lithography Enables Cost-Effective Photonics Production
Feb 13, 2015 — The ability to create wafer-scale stitching-error-free patterns of nanostructures on bowed and warped surfaces and even on topography, as well as direct patterning of 3-D structures, makes nanoimprint lithography ideally suited for the needs of a...
Film Enables Touch Displays That Respond to Bending, Heat
WURZBURG, Germany, Feb. 6, 2015 — A novel film could be used to make flexible displays that respond not only to touch but also to bending. Developed by a team from the Fraunhofer Institute for Silicate Research (ISC), the film is based on piezoelectric printing pastes that render...
Quantum Materials Begins Shipping of Cadmium-Free QDs
SAN MARCOS, Texas, Feb. 5, 2015 — Quantum Materials Corp. has begun shipping cadmium-free red and green quantum dots in evaluation and production quantities to consumer electronics manufacturers. The company said a new facility, equipment and personnel have allowed it to increase...
