The intrinsic physical characteristics of optical fiber combined with its versatility in remote sensing make it an attractive technology for biomedical applications.
A collaborative effort from researchers at the Harvard School of Public Health, Beth Israel Deaconess Medical Center, Massachusetts Institute of Technology, and the German Research...
Fabrication of negative-index metamaterial (NIM) lenses (which can image beyond the diffraction limit) has made progress, but the creation of such lenses for the visible spectrum...
Many optical sensors rely on the detection of small wavelength changes in response to changes in temperature, strain, adhesion of bioparticles, or change in the chemical environment...
I read the news item in Laser Focus World [p. 18, November 2010] of the femtosecond news section, entitled "Laser pulse filaments produce Hawking radiation."
Optical fiber with a semiconductor core has the potential to unify long, flexible, and robust fiber-based waveguides with the nonlinear, Raman, and infrared transparency of semiconducto...
Europe's ambitious program to develop short-pulse, high-intensity lasers begins work on three petawatt-class lasers this year. These lasers will point the way to plans for a 200...
Hypersonic air and space vehicles include the Space Shuttle and the US Air Force X-37B, which both re-enter the atmosphere at Mach 25 before slowing to subsonic speeds.
Raising money is never easy for any business. The last three years have been especially challenging. Recently a number of successful IPOs and M&As have made the outlook more positive...
Immersion lithography at ultraviolet (UV) wavelengths has been used extensively to create wire-grid polarizers consisting of parallel lines of aluminum or some other metal on ...
