Researchers steer light in new directions

A team of researchers led by San Francisco State University's Weining Man is the first to build and demonstrate the ability of two-dimensional disordered photonic band gap material, designed to be a platform to control light ...

Wideband wavelength conversion using cavity optomechanics

A team of researchers at the NIST Center for Nanoscale Science and Technology (CNST), the University of Maryland, and the California Institute of Technology have demonstrated optical wavelength conversion using interactions ...

Optics: Nanotechnology's benefits brought into focus

Conventional lenses, made of shaped glass, are limited in how precisely they can redirect beams of incoming light and make them meet at a point. Now, a team led by Zhengtong Liu at the A*STAR Institute of High Performance ...

NRL develops low cost, high efficiency solar sensor

Research scientists at the U.S. Naval Research Laboratory (NRL) Electronics Science and Technology Division have developed a novel low cost, highly efficient spectral sensor for field analysis of solar cell irradiance performance ...

A new light wave

Hold a magnifying glass over the driveway on a sunny day and it will focus sunlight into a single beam. Hold a prism in front of the window and the light will spread out into a perfect rainbow. Lenses like these have been ...

Chandra sees eclipsing planet in X-rays for first time

For the first time since exoplanets, or planets around stars other than the sun, were discovered almost 20 years ago, X-ray observations have detected an exoplanet passing in front of its parent star.

New phenomenon could lead to novel types of lasers and sensors

There are several ways to "trap" a beam of light—usually with mirrors, other reflective surfaces, or high-tech materials such as photonic crystals. But now researchers at MIT have discovered a new method to trap light that ...
