‘Air Laser’ Sniffs Bombs, Pollutants from Afar
PRINCETON, N.J., Feb. 1, 2011 — A new laser sensing technology that generates a laser beam out of thin air may allow soldiers to detect hidden bombs from a distance and scientists to better measure airborne environmental pollutants and greenhouse gasses. Researchers at Princeton University developed a technique for generating a laser beam out of nothing but air. They focus a pump laser on a distant point in the air and another laser beam comes back. The image shows a pulse of infra-red light from this "air laser." The center...
A supercool new scanning probe microscope
GAITHERSBURG, Md. – A new ultra-low-temperature scanning probe microscope is being billed by its creators as the most advanced in the world. The microscope, dubbed ULTSPM, was developed by researchers at the National Institute of Standards and Technology (NIST), the...
Assessing water quality with fluorescence
RESTON, Va. – Fluorescence measurements could help scientists monitor source water quality, according to a recent US Geological Survey (USGS) study of Oregon’s McKenzie River. The focus of the study was the type, amount and source of dissolved organic...
Creating multimetal nanoparticles
RALEIGH, N.C. – Digestive ripening, a technique used to make single-metal nanoparticles, also can be extended to create nanoparticles that consist of two metals and that also have tunable properties, according to a study from researchers at North Carolina State...
Highly unidirectional “whispering gallery” microlasers
CAMBRIDGE, Mass. – Highly collimated unidirectional microlasers have been demonstrated, and their creators say they will have a wide range of new photonics applications, including sensing and communications. Researchers at Harvard University, in collaboration with...
Laser light shows for quantum computing
DURHAM, N.C., and MADISON, Wis. – Quantum computers have moved a step closer with a beam-steering system that can focus bursts of laser light onto single atoms. The system can be compared to the projectors used in laser light shows, but it is far faster and smaller, and accurate to...
Nanoscale 3-D images shed light on Earth’s core
PALO ALTO, Calif. – Physicists can study the Earth’s inner history, thanks to a technique that provides a picture of minerals interacting at ultrahigh temperatures and pressures. The new method, high-pressure nanoscale x-ray computed tomography, is being...
Plasmon lasers at room temperature
BERKELEY, Calif. – A new technique allows plasmon lasers to operate at room temperature, a “major step toward applications” for the lasers, according to Xiang Zhang, principal investigator, who is also a University of California professor of mechanical...
Practical, tunable 3-D microdroplet laser
LJUBLJANA, Slovenia – Electronics could get smaller, faster, cheaper to make and higher in precision, thanks to a microdroplet 3-D laser system. “This is the first practical 3-D laser ever produced,” said Igor Musevic, who developed the laser with Matjaz...
Single QD nanowire photodetectors
DELFT, Netherlands – In another step toward quantum computing, researchers have made a photodetector based on a single nanowire, in which the active element is a single quantum dot (QD) with a volume of only 7000 nm3. The nanowire, which was made of indium phosphide,...
Smaller features, faster wafers
WEST LAFAYETTE, Ind. – As Moore’s law – the doubling every two years of the number of transistors on an integrated circuit – moves closer and closer, the semiconductor industry is looking for ways to make microchips faster and faster. And a new 13.5-nm...
Solid-state terahertz lasers warm up
BOSTON – Terahertz rays have proved hard to generate cost-effectively, as solid-state lasers so far have been unable to produce terahertz rays without supercooling. Some physicists even have speculated that frequency and temperature are linked by some...
Stable optical lift proved
ROCHESTER, N.Y. – The existence of stable optical lift, or the use of a beam of light to move and manipulate particles in the micrometer scale, has finally been proved. Applications include astrophysics, biotechnology and microelectronics. Someday it could be used to...
Type-II InAs/GaSb superlattices lead to new IR camera
EVANSTON, Ill. – A novel IR camera based on Type-II InAs/GaSb superlattices produces images with much higher resolution than previous IR cameras could produce. The camera’s long-wavelength IR (LWIR) focal plane array can provide IR images in the dark and...
NRL Field Tests Laser Acoustic Propagation
CRANE, Ind., Jan. 31, 2011 — A research team at the Naval Research Laboratory (NRL) led by physicist Dr. Ted Jones of the Plasma Physics Division, performed the first successful long distance acoustic propagation and shock generation demonstration of their novel underwater...
SPIE Photonics West Attendance Breaks Records
SAN FRANCISCO, Jan. 31, 2011 — With approximately 19,390 presenters, exhibitors and visitors, attendance at SPIE Photonics West grew six percent this year, event organizers said. SPIE Photonics West, the leading photonics, laser, and biomedical optics event, took place Jan. 22-27...
Turning Gold to Purple to Harvest Sunlight
PROVO, Utah, Jan. 31, 2011 — Professor Richard Watt and his chemistry students at Brigham Young University suspected that a common protein could potentially react with sunlight and harvest its energy — similar to what chlorophyll does during photosynthesis. They...
Mix of Nanoparticles, DNA Create Photonic Crystals
ROCHESTER, N.Y., Jan. 28, 2011 — Scientists have created a diamond-like lattice composed of gold nanoparticles and viral particles, woven together and held in place by strands of DNA. The structure — a distinctive mix of hard, metallic nanoparticles and organic viral pieces...
A Practical Full-spectrum Solar Cell Nears
BERKELEY, Calif., Jan. 27, 2011 — A solar cell that not only responds to virtually the entire solar spectrum, but can also readily be made using one of the semiconductor industry’s most common manufacturing techniques has been demonstrated by a team at Lawrence Berkeley...
GRIN Plasmonics: A Path to Superfast Computing
BERKELEY, Calif., Jan. 27, 2011 — A team of researchers with the US Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California, Berkeley, have carried out the first experimental demonstration of GRIN – for gradient...
Laser-treated Parchment Creates Microfluidic Device
WEST LAFAYETTE, Ind., Jan. 26, 2011 — Using lasers to create patterns on common parchment paper, researchers are now able to make "microfluidic" devices for rapid medical diagnostics and chemical analysis. The innovation represents a way to enhance commercially available diagnostic...
Perspectives on the Si Photonics Frontier
SAN FRANCISCO, Jan. 26, 2011 — Because a new market of miniaturized low-cost photonics will soon be created that can leverage the vast scale of CMOS manufacturing to revolutionize industries from computing and communication to biomedicine and imaging, panelists representing...
