The next time an overnight snow begins to fall, take two bricks and place them side by side a few inches apart in your yard.In the morning, the bricks will be covered with snow and barely discernible. The snowflakes will have filled every vacant space between and around the bricks.What you will see, says Ivan Biaggio, resembles a phenomenon that, when it occurs at the smallest of scales on an integrated optical circuit, could hasten the day when the Internet works at superfast speeds.Biaggio,...

Scientists at the University of Konstanz in Germany and the National Institute of Standards and Technology (NIST) have demonstrated an ultrafast laser that offers a record combination of high speed, short pulses and high average power. The same NIST group also has shown that this type of laser, when used as a frequency comb"”an ultraprecise technique for measuring different colors of light"”could boost the sensitivity of astronomical tools searching for other Earthlike planets as...

Photoconducting polymers doped with nonlinear optical chromophores have emerged as efficient and inexpensive photorefractive (PR) materials. These materials show promise for applications in dynamic volume holography, image formation, optical processing, reversible data storage, correlation, etc. Recently, PR polymer composites have gained a great amount of attention due to their large PR effect, structural flexibility, and good processability. J. L. Maldonado, G....

NIST -- The world's most accurate "ruler" made with extreme ultraviolet light has been built and demonstrated with ultrafast laser pulses by scientists at JILA, a joint institute of the National Institute of Standards and Technology (NIST) and the University of Colorado at Boulder. The new device, which consistently generates pulses of light lasting just femtoseconds (quadrillionths of a second, or millionths of a billionth of a second) in the ultraviolet region of the electromagnetic...

COLLEGE STATION -- Engineers and applied physicists have laid the foundations for a new type of "plug and play" laser -- the Raman injection laser -- and in the process, several key innovations in laser technology. The device combines the advantages of nonlinear optical devices and semiconductor injection lasers with a compact design, and may one day lead to wide-ranging applications in imaging and detection. Published in the Feb. 24th issue of Nature, the proof of concept model was developed...

Word of the Day
  • Licking.
  • Hence Running along or over a surface, as if in the act of licking; flowing over or along; lapping or bathing; softly bright; gleaming.
This word comes the Latin 'lambere,' to lick.
