Researchers using nanotechnology have taken a step toward creating an "optical cloaking" device that could render objects invisible by guiding light around anything placed inside this "cloak."
A new science 'biophotonics' has a new center of operations. Quarters for the National Science Foundation-funded UC Davis Center for Biophotonics Science and Technology were dedicated Monday in the Oak Park Research Building at 2700 Stockton Blvd.
For those who've reached the age when reading a newspaper means holding it at arm's length or fumbling for reading glasses, wavefront-optimized lens technology may offer a better solution, according to data presented at the recent American Academy of Ophthalmology's 2006 Joint Meeting.
The Internet is often called the information superhighway, but the real superhighway is the optical fiber that connects computers around the world at the speed of light, according to John Badding, Penn State associate professor of chemistry.
In an effort to combine sophisticated laser and Internet technologies, scientists in Australia have successfully performed laser surgery and "optical trapping" in a Southern California laboratory via the Internet.
Increasing interest has focused recently on ways of drastically slowing light or, more precisely, the speed of laser data pulses - and a joint USC/Duke University team has just reported improvements in a way to do this in a flexible and controlled manner.
"Black gold" is not just an expression anymore. Scientists at the University of Rochester have created a way to change the properties of almost any metal to render it, literally, black.
Using laser pulses that last just 70 femtoseconds (quadrillionths of a second), physicists have observed in greater detail than ever before what happens when atoms collide.
In what promises to be an important advance, researchers at the University of California, Santa Barbara have developed a novel laser by bonding optical gain layers directly to a silicon laser cavity.
A UC Irvine ophthalmologist and his team have invented a new laser-surgery technique to perform cornea-transplant surgery that can replace the use of traditional handheld surgical blades and potentially improve recovery time for patients.
