Using invisibility to increase visibility
Research into the development of invisibility devices has spurred two physicists' thought on the behaviour of light to overcome the seemingly intractable problem of optical singularities which could soon lead to the manufacturing of a perfect cat's eye. view more (2008-12-01)
Scientists closer to making invisibility cloak a reality
J.K. Rowling may not have realized just how close Harry Potter's invisibility cloak was to becoming a reality when she introduced it in the first book of her best-selling fictional series in 1998. Scientists, however, have made huge strides in the past few years in the rapidly developing field of cloaking. Ranked the number five breakthrough of... view more... (2009-03-06)
Collaboration shines possible light on objects 'weirder than black holes'
Researchers from Duke University and the University of Cambridge think there is a way to determine whether some black holes are not actually black. view more (2007-09-25)
Finding out what the Big Bang and ink jets have in common
It often turns out there is more to commonplace everyday events than meets the eye. The folding of paper, or fall of water droplets from a tap, are two such events, both of which involve the creation of singularities requiring sophisticated mathematical techniques to describe, analyse and predict. view more (2008-06-04)
Optical Atomic Clock: A long look at the captured atoms
Optical clocks might become the atomic clocks of the future. Their "pendulum", i.e. the regular oscillation process which each clock needs, is an oscillation in the range of the visible light. view more (2008-02-06)
Making monster waves
Rogue waves-giant waves that spring up suddenly and tower over the seas around them-have inspired physicists to look for an analogue in light. view more (2009-10-20)

Polarization holographic device using photoreactive polymer liquid crystals
Photo-control of molecular orientation of polymer materials is of great interest for the development of highly functionalized holographic optical devices. view more (2005-10-19)
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)
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 „MELEMECH", sponsored by the federal German... 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 University of Warwick`s Engineering Department. It... 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 between the observatories and the universities who have... view more... (2004-01-26)
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)
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 also of interest as optoelectronic components. One... view more... (2002-03-07)
Engineers demonstrate a new type of optical tweezer
Researchers at the Harvard School of Engineering and Applied Sciences (SEAS) demonstrated a new type of optical tweezer with the potential to make biological and microfluidic force measurements in integrated systems such as microfluidic chips. view more (2008-02-26)
Bristleworms engineer optics - Photon02
Computer and optical communications engineers are now using optical structures to produce faster, more powerful, light-based processors and networks. However, according to Dr Andrew Parker from Oxford University, they are well behind the times as nature has been making these optical structures for at least 515 million years. He and his team are... view more... (2002-08-28)
Single-Crystal Semiconductor Wire Built into an Optical Fiber
An international science team from Penn State University in the United States and the University of Southampton in the United Kingdom has developed a process for growing a single-crystal semiconductor inside the tunnel of a hollow optical fiber. The device adds new electronic capabilities to optical fibers, whose performance in electronic devices... view more... (2008-03-13)
Promise shown for data encryption and data storage using holograms
The rapidly developing digital age demands greater processing power, data storage and data encryption for computer based technologies. Recent developments point towards optical information processing as a great leap forward. view more (2006-03-28)
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 allow enhancement of the display of the movement... 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 insect might develop sublethal infections, rather... view more...
