At St. Paul's Cathedral in London, a section of the dome called the Whispering Gallery makes a whisper audible from the other side of the dome as a result of the way sound waves travel around the curved surface. Researchers at Washington University in St. Louis have used the same phenomenon to build an optical device that may lead to new and more powerful computers that run faster and cooler. Lan Yang, PhD, associate professor of electrical and systems engineering, and her collaborators...

A Feeling For The 'Light' Wave
2014-01-13 12:55:37

Max-Planck-Institute of Quantum Optics A team in the Laboratory for Attosecond Physics (LAP) at the Max-Planck-Institute of Quantum Optics has taken another step toward the achievement of complete control over the waveform of pulsed laser light. Together with colleagues based at LMU and the Technische Universität München (TUM), they have constructed a detector which provides a detailed picture of the waveforms of laser pulses that last for a few femtoseconds (1 fs = 10-15 seconds)....

Development of electronics and communication requires a hardware base capable for increasingly larger precision, ergonomics and throughput. For communication and GPS-navigation satellites, it is of great importance to reduce the payload mass as well as to ensure the signal stability. Last year, researchers from the Moscow State University (MSU) together with their Swiss colleagues from EFPL performed a study that can induce certain improvements in this direction. The scientists demonstrated...

Ten Times More Throughput On Optic Fibers
2013-12-04 12:56:47

Ecole Polytechnique Fédérale de Lausanne EPFL scientists have shown how to achieve a dramatic increase in the capacity of optical fibers; Their simple, innovative solution reduces the amount of space required between the pulses of light that transport data Optical fibers carry data in the form of pulses of light over distances of thousands of miles at amazing speeds. They are one of the glories of modern telecommunications technology. However, their capacity is limited, because the...

Intense 2-color Double X-ray Laser Pulses Generated For First Time
2013-12-04 12:47:43

RIKEN A team working at the SACLA X-ray Free-Electron Laser (XFEL) in Japan has succeeded in generating ultra-bright, two-color X-ray laser pulses, for the first time in the hard X-ray region. These light pulses with different wavelengths, whose time separation can be adjusted with attosecond accuracy, are very powerful tools to investigate the structure of matter and the dynamics of ultrafast physical processes and chemical reactions. SACLA is one of only two facilities in the world to...

PORTLAND, Ore., Sept. 11, 2013 /PRNewswire/ -- Portland laser start-up, FiLaser has successfully licensed a key patent from the University of Toronto (U of T), effectively enabling it to control so-called Burst-Pulse Laser Machining in the USA and Canada. Through a commercial arrangement, FiLaser has negotiated exclusive access to this technology as it relates to the company's approach to cutting and drilling brittle materials, such as glass and silicon. "The technique involves...

Removing the “Random” Out Of A Random Laser
2013-07-15 14:43:30

Vienna University of Technology Random Lasers are tiny structures emitting light irregularly into different directions. Scientists at the Vienna University of Technology have now shown that these exotic light sources can be accurately controlled. The light they emit is as unique as a fingerprint: random lasers are tiny devices with a light emission pattern governed by random scattering of light. Understanding the underlying details of random lasing action has only been achieved...

Laser frequency combs-high-precision tools for measuring different colors of light in an ever-growing range of applications such as advanced atomic clocks, medical diagnostics and astronomy-are not only getting smaller but also much easier to make. Physicists at the National Institute of Standards and Technology (NIST) can now make the core of a miniature frequency comb in one minute. Conventional microfabrication techniques, by contrast, may require hours, days or even weeks. The NIST...
