Laser plasma process could advance optoelectronic materials
MONTREAL – A novel nanohybrid structure synthesized using a pulsed laser ablation technique could yield a new generation of optoelectronic switches, fast photodetectors and third-generation solar devices. Research on the photoelectronic properties of...
Nanotubes on a chip simplify optical power measurements
GAITHERSBURG, Md. – A chip-scale instrument made of carbon nanotubes may simplify absolute measurements of laser power, especially the light signals transmitted by optical fibers in telecommunication networks. A prototype device developed at the National Institute of...
On-chip detector reliably finds single photons
KARLSRUHE, Germany – Single photons can be reliably detected for data transmission and quantum computing by integrating detectors with nanophotonic chips, an international team has discovered. Ultrafast, efficient and reliable single-photon detectors suitable for...
Optical fibers may transport quantum information
INNSBRUCK, Austria – Optical fibers, which transport data around the world, now may be able to carry quantum information, according to new research. Rainer Blatt and Tracy Northup of the University of Innsbruck have directly transferred the quantum information stored in...
Rare mineral yields light-emitting nano triangles
UNIVERSITY PARK, Pa. – A rare mineral formed into single sheets produces triangular structures with unusual light-emitting properties that could be used in optical technologies such as light detectors or lasers. Creating single, one-atom-thick layers, or monolayers, is of...
Silica’s compatibility broadens through self-assembly
SYDNEY and PARIS – Silica, a rugged compound with unbeatable optical transparency over long distances, is about as easy to combine with other materials as oil is with water. But a novel manufacturing technique transforms this underused cousin of optical fiber into...
Solar Cells Derived from Trees
ATLANTA, April 1, 2013 — Just as leaves capture sunlight and convert it to energy, so do solar cells, and now recyclable, sustainable and renewable photovoltaics can be made using natural substrates derived from trees.
Supernanograting enables spectrometer sensor
HUNTSVILLE, Ala. – Combining nanophotonics technology with traditional optical spectroscopy has yielded a new kind of optical spectrometer with sensing and spectral measurement functions. Traditional optical spectrometers measure the spectra of light; traditional...
Collaboration Makes Easily Manufactured Optical Metamaterials
UNIVERSITY PARK, Pa., March 29, 2013 — Controlling the optics of metamaterials involves using complicated structures that are difficult to manufacture in large numbers and at small sizes at optical wavelengths. However, engineers are collaborating to change that with a nanonotch,...
Study Proposes Fiber-laser-based Particle Accelerator
SOUTHAMPTON, England, March 29, 2013 — An international study proposing that a massive fiber laser system could produce the next-generation particle accelerator has now been published.
‘Bulk’ Silicon Emits Visible Light
PHILADELPHIA, March 28, 2013 — With silicon entrenched as the material of choice for the electronics industry, augmenting its optical properties so it could be integrated into photonic circuitry would make consumer-level applications of the technology more feasible. Now, for the...
Open-Source 3-D Printable Optics Library Introduced
HOUGHTON, Mich., March 28, 2013 — A library of open-source, 3-D printable optics components could slash optics laboratory costs by as much as 97 percent, expanding access to a broader audience than previously possible.
Glasses-Free 3-D Display Well Suited for Mobile Devices
PALO ALTO, Calif., March 27, 2013 — A new glasses-free 3-D display based on diffractive optics modulates at video rates and shows images that can be viewed from multiple angles even when the display is tilted, making it well suited for mobile devices.
Light and Color Measure Cell O2 in Real Time
ST. LOUIS, March 27, 2013 — A real-time technique that uses light and color to measure oxygen delivery to individual red blood cells could enable researchers to study the process in relation to diseases and their treatments.
Simulations Uncover Obstacle to Harnessing Laser-driven Fusion
COLUMBUS, Ohio, March 27, 2013 — A once-promising approach for using next-generation, ultra-intense lasers to help deliver commercially viable fusion energy has been brought into serious question by new experimental results and first-of-a-kind simulations of laser-plasma...
‘Metascreen’ Forms Ultrathin Invisibility Cloak
AUSTIN, Texas, March 26, 2013 — A new ultrathin Harry Potterlike invisibility cloak can hide three-dimensional objects from microwaves while in their natural environment, in all directions and from all of the observers’ positions.
