Optical cloaking approach described in Optics Express shows potential for myriad futuristic applications Invisibility cloaks are seemingly futuristic devices capable of concealing very small objects by bending and channeling light around them. Until now, however, cloaking techniques have come with a significant limitation"”they need to be orders of magnitude larger than the object being cloaked. This places serious constraints on practical applications, particularly for the...

In an advance that sounds almost Zen, researchers at the National Institute of Standards and Technology (NIST) and JILA, a joint institute of NIST and the University of Colorado at Boulder, have demonstrated a new type of pulsed laser that excels at not producing light. The new device generates sustained streams of "dark pulses""”repeated dips in light intensity"”which is the opposite of the bright bursts in a typical pulsed laser. Despite its ominous name, the dark pulse laser is...

Researchers at the University of Rochester's Institute of Optics have discovered a way to make liquid flow vertically upward along a silicon surface, overcoming the pull of gravity, without pumps or other mechanical devices. In a paper in the journal Optics Express, professor Chunlei Guo and his assistant Anatoliy Vorobyev demonstrate that by carving intricate patterns in silicon with extremely short, high-powered laser bursts, they can get liquid to climb to the top of a silicon chip like it...

Scientists and curiosity seekers who want to know what a partially or completely cloaked object would look like in real life can now get their wish -- virtually. A team of researchers at the Karlsruhe Institute of Technology in Germany has created a new visualization tool that can render a room containing such an object, showing the visual effects of such a cloaking mechanism and its imperfections. To illustrate their new tool, the researchers have published an article in the latest issue of...
