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 optically encoded audio recording using a plasmonic nanostructure. Using the device as a “nano piano,” they were able to input and then play back the melody of “Twinkle, Twinkle, Little
Livermore Pushes Beyond Flashlamps to Boost Laser Repetition Rates
LIVERMORE, Calif., March 13, 2015 — The world’s highest-peak-power laser diode arrays are now online at Lawrence Livermore National Laboratory. The 3.2-MW arrays are destined to become part of the High-Repetition-Rate Advanced Petawatt Laser System (HAPLS) in 2017. Livermore has...
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...
Photothermal Nanoparticles Extend Range of Optogenetics
CHICAGO, March 12, 2015 — Targeted gold nanoparticles allow light to activate neurons, a finding that could enable the use of optogenetic techniques without genetic manipulation. “This is effectively optogenetics without genetics,” said professor Dr. Francisco...
Chalcogenide Fibers Mimic Brain Functions
SOUTHAMPTON, England, March 10, 2015 — Chalcogenide microfibers could be used to replicate the workings of the human brain, enabling optical computers capable of learning and evolving. A variety of broadband photoinduced effects allow metal-sulfide fibers to be switched on and off. This...
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,...
Phase Encoding, Photon Counting Yield Secure QR Codes
STORRS, Conn., March 4, 2015 — Microscale QR codes coupled with optical phase encoding and photon-counting encryption could be used to protect the integrity of microchips used in the most sensitive applications. QR, or Quick Response, codes — those black and white boxes...
Light’s Wave-Particle Duality Visualized (with video)
LAUSANNE, Switzerland, March 3, 2015 — A novel imaging approach has brought light’s split personalities together for the first time. The wave-particle duality of light is well known, though experiments to date have only been able to observe one property at a time. But now a team of...
Modified Genes Triggered by Blue Light
DURHAM, N.C., March 2, 2015 — Crossing a bacterium’s viral defense system with a flower’s response to the sun yields a light-based trigger for genes. This type of control could enable deeper study of specific genes’ functions, create complex systems for growing...
Nanostructures Enable Step Toward OLED Lasers
SANTA BARBARA, Calif., March 2, 2015 — Organic LEDs made with finely patterned nanostructures can produce bright, low-power light sources, a key step toward making organic lasers. Researchers have long dreamed of building organic lasers, but they have been hindered by carbon-based...
Tyndall to Lead $6M Project on Photonic Circuits for Data Transmission
CORK, Ireland, March 2, 2015 — The Tyndall National Institute will lead a consortium of researchers in a three-year, €5.2 million (about $5.95 million) European Union-funded project to develop photonic circuits for faster, cheaper data transmission. The Thermally Integrated...
Germany Opens Digital Photonic Production Research Campus
AACHEN, Germany, Feb. 27, 2015 — Government, scientific and industry leaders recently opened the Digital Photonic Production research campus to develop light as a production tool. The German Federal Ministry of Education and Research (BMBF) is funding nine such research campuses...
Printable Filters Manage THz Communications
SALT LAKE CITY, Feb. 27, 2015 — Filters created with an off-the-shelf inkjet printer could enable blazing-fast wireless downloads and clearer cellphone calls using the terahertz spectrum. University of Utah researchers developed the filters, which are created with silver-metal ink...
Cubic Nanoantennas Eyed for NEMS Biosensors
CLAYTON, Victoria, Australia, Feb. 24, 2015 — Lab-on-a-chip applications could benefit from cubical nanoantennas that direct light more effectively than spherical ones. The cubes, which are composed of insulating rather than conducting or semiconducting materials, are easier to fabricate and...
Model Predicts Metamaterials’ Nonlinear Optical Properties
BERKELEY, Calif., Feb. 23, 2015 — A new approach that can predict the nonlinear light scattering properties of nanoscale objects could help turn optical metamaterials to more practical uses. The unique electromagnetic properties of metamaterials stem from their physical structure...
‘Flat Lens’ Masters Chromatic Aberration
CAMBRIDGE, Mass., Feb. 19, 2015 — Overcoming a limitation of earlier flat optics, a new achromatic metasurface is able to bend different wavelengths of light by the same amount. The ultrathin “flat lens” is composed of a glass substrate and nanoscale silicon optical...
Laser Frequency Comb Boosts Solar Telescope Accuracy (with video)
MUNICH, Feb. 18, 2015 — Laser frequency combs can help telescopes achieve unprecedented accuracy in spectral measurements, and may someday aid detection of Earth-sized exoplanets. A team from three German institutions attached a laser frequency comb to the Kiepenheuer...
ZnO Nanowires Create Ultrasensitive UV Smoke Detector
SURREY, England, Feb. 17, 2015 — A new low-temperature nanowire growth process can create ultrasensitive UV sensors for fire detection directly on a microchip. A ZnO nanowire detector created through a seedless hydrothermal technique is 10,000 times more sensitive to UV radiation...
