Silicon photonic crystals key to optical cloaking, researchers say
In computer simulations, the researchers have demonstrated an approximate cloaking effect created by concentric rings of silicon photonic crystals. The mathematical proof brings scientists a step closer to a practical solution for optical cloaking.   view more (2008-06-26)

Engineers create 'optical cloaking' design for invisibility
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."   view more (2007-04-03)

The Mathematics of Cloaking
The theorists who first created the mathematics that describe the behavior of the recently announced "invisibility cloak" have revealed a new analysis that may extend the current cloak's powers, enabling it to hide even actively radiating objects like a flashlight or cell phone.   view more (2006-12-27)

Invisibility undone
Harry Potter beware! A team of Chinese scientists has developed a way to unmask your invisibility cloak.

UCSB researchers develop hybrid silicon evanescent laser
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.   view more (2005-11-16)

New research field promises radical advances in optical technologies
A new research field called transformation optics may usher in a host of radical advances including a cloak of invisibility and ultra-powerful microscopes and computers by harnessing nanotechnology and "metamaterials."   view more (2008-10-17)

Hanover Trade Fair 2003: Getting to grips with optical fibres
A vacuum gripper mounts optical waveguides exactly right on the micrometre Microtechnological precision components from the production line - up to date, the realisation of this vision lacked the tools and technologies for automated manufacturing. Therefore, the aim of the research project... view more (2003-04-07)

New Optical Antenna Brings Massive Benefits to Wireless Networks, Household Electronics and Longer Distance Data Transfer
A new optical antenna, developed by researchers at the University of Warwick, will bring significant benefits to credit card payments, wireless networks, household electronics and longer distance data transfer. The device was developed by Professor Roger Green and Roberto Ramirez-Iniguez, in the... view more (2002-11-07)

A technological breakthrough for radio astronomy - Astronomical observations via high-speed data link
To carry out simultaneuos observations with several telescopes and transform the combined data into pictures from distant galaxies has so far been a cumbersome procedure which often has taken a long time. Now a breakthrough has been achieved by way of the installation of optical fibre links... view more (2004-01-26)

Scientists step closer to realising invisible technology
A unique computer model designed by a mathematician at the University of Liverpool has shown that it is possible to make objects, such as aeroplanes and submarines, appear invisible at close range.   view more (2007-05-04)

CT colonoscopy has 90 percent agreement rate with optical colonoscopy
Nearly 90% of colon polyps greater than or equal to 6 mm in size detected at CT colonoscopy were demonstrated to represent true polyps at subsequent optical colonoscopy (the traditional method of viewing the colon and removing precancerous growths).   view more (2007-05-07)

New metamaterials that bend light backwards bring invisibility cloaks 1 step closer
Scientists at the University of California, Berkeley, have for the first time engineered 3-D materials that can reverse the natural direction of visible and near-infrared light, a development that could help form the basis for higher resolution optical imaging, nanocircuits for high-powered... view more (2008-08-11)

Electric Nudge toward Self-organization
In search of materials with nonlinear optical properties Window panes and eyeglass lenses that get darker as it gets brighter are especially great in the summer. Their secret lies in optical properties that change as the light intensity changes - nonlinear optical properties. Such materials are... view more (2002-03-07)

Image Velocity Estimation In Echocardiographs
BACKGROUND There are many instances in which a subject in an image is moving, and it is necessary to track the subject as it moves from frame to frame; this movement is known as optical flow or image velocity. Such measurement of optical flow may be done to improve the image encoding efficiency, or... view more (2005-04-26)

Optical brighteners for bioinsecticides
Optical brighteners are a valuable component for bioinsecticide formulae based on baculovirus. These substances enhance their insecticidal capacity at the same time as they do not favour the development of resistance of the insects to these viruses, nor do they increase the probability that the... view more (2004-09-06)

Turning sound into light
Actors who perform in musicals often sweat in torrents when they have to zap around the stage on roller-skates or sing a ballad under a burning spotlight, dressed in bearskin. To allow the audience to hear them clearly, the artists wear cleverly hidden microphones underneath their make-up and... view more (2003-09-18)
