It's often a case of swings and roundabouts. If you save money by buying a house out of town, you spend more time and money commuting. If you really measure the momentum of an electron, you have no idea where the little guy is located. And now, according to a new analysis by a pair of University of Texas electrical engineers, the better an object is hidden by an invisibility cloak at a given wavelength of light, the easier it is to see at other wavelengths. Swings and roundabouts.  Read More

A new optical disc uses QR codes etched in tungsten to achieve extreme levels of heat resi...

A researcher at the University of Twente in the Netherlands has developed a new optical memory disc out of tungsten and silicon nitride that he says could store data safely for extremely long periods of time – up to a billion years.  Read More

One example of biomimicry that keeps popping up on the pages of Gizmag is the use of insect eyes as a model for innovative new optical devices. It seems that the potential for development in this area is far from exhausted with the announcement of another bug-inspired lens breakthrough from Ohio State University. This experimental lens developed by associate professor of biomedical engineering and ophthalmology, Yi Zhao, combines the wide angle properties of insect vision with the depth-of-field capabilities of a human eye.  Read More

Researchers from the University of Minnesota and Seoul National University have developed a new lithographic method with the help of a very low-tech tool: Scotch Magic tape. This new method, which promises to enhance our ability to fabricate nanostructures, has been used to build highly nonlinear optical materials consisting of sheets of 25 micron (0.001 in) metal blocks separated by nanometer-wide insulating channels. As light squeezes through these channels, incompletely understood plasmonic effects enable novel optical behavior.  Read More

Astronomers have developed a new visible-light adaptive optics (AO) system for the 6.5 meter diameter Magellan-Clay telescope in Chile's Atacama desert. The new AO system replaces the secondary mirror of the telescope with a thin adaptive mirror that can be deformed by its 585 mechanical actuators at a rate of more than 1000 times a second to correct for the image smearing effects of atmospheric turbulence. The result is the sharpest astronomical images ever produced – more than twice as sharp as can be achieved by the Hubble space telescope viewing objects through the vacuum of space.  Read More

Researchers at the Technische Universität Darmstadt in Germany have managed to stop light for up to one minute inside a crystal and store digitally-encoded information inside it. The technique shatters previous records and could prove very useful in developing faster and highly-efficient quantum and optical computers.  Read More

A recent optical disc archive system from Sony

Technology giants Sony and Panasonic are joining forces to create a single optical disc with 300 GB of capacity by 2015. Both companies have developed their own high capacity optical disc technology in the past, and the joint venture will aim to create a new format to target large amounts of storage for corporations, though it could be introduced into the consumer market as well.  Read More

Graphene continues to strengthen its reputation as a wonder material, this time in the fie...

Researchers from the Universities of Bath and Exeter have shown that a few layers of graphene stacked on top of each other could act as a formidable material for optical switches, delivering speeds up to 100 times faster than current telecommunications technology.  Read More

Super-black nanotechnology might sound like something ripped from the pages of a comic book, but instead of being in the hands of a super-villain, it's a NASA-researched technology that is set to make spacecraft instruments more sensitive without increasing their size. John Hagopian, an optics engineer at NASA's Goddard Space Flight Center, and his team have demonstrated the ability to grow a uniform layer of carbon nanotubes on oddly shaped platforms, which will extend the potential of the technology by allowing nanotubes to be grown on 3D components.  Read More

Recently, there have been advances in the area of digital data storage promising outstanding data density and super-long-term data storage. A new data storage technology developed at the University of Southampton can do both. Due to its similarities to the “memory crystals” used in the Superman films, it has been dubbed the "Superman memory crystal."  Read More
