Future Projections: Cell Phone Market Poised for Projectors The market for tiny handheld projectors, known as pico projectors, began in earnest a few years ago, with companies like Microvision Inc., Explay and 3M introducing prototypes at industry events such as the 2008 Consumer Electronics Show (CES). Shortly after, industry wags began writing that consumers would soon be able to buy cell phones and other electronic devices containing embedded...
For Nonlinear Optical Processing, Things Do – and Don’t – Add Up Sometimes you don’t want 2 + 2 to equal 4. Instead, it would be nice if the result were a lot more – or a lot less. That’s the basis for nonlinear optical processing, where a...
Putting the “Eye” in CSI Forensic investigation hasn’t yet achieved the sci-fi type of technological sophistication seen on CSI and other television crime shows, but it’s getting there. Having seen what is...
Monolithic Photonic Integrated Circuits for 10G Passive Optical Networks Continually escalating demands for broader penetration of higher bandwidth, faster performance and rich-media applications are driving the ongoing worldwide deployment of fiber-based services. Even...
High-Energy Laser Optics Require Coatings in Their Own League Sure, your laser pointer doesn’t have the power to punch through the wall, but high-fluence CO2 and other heavy-duty beasts of burden can carve through sheet metal, slice 1/4-in. steel into...

Curved light bends the rules Conventional thinking leads us to believe that light only follows a straight path and that it diffracts as it travels. But some scientists are breaking all the rules by creating a new class of nondiffracting optical beam that can bend around corners. These rays are called “Airy beams,” a name that honors the English astronomer Sir George Biddell Airy for his studies of the parabolic...
Sound helps make a better optical clock Optical fibers are commonly used to transmit information and data via modulated light pulses. Now, however, three researchers at Physikalisch-Technische Bundesanstalt (PTB), working with optical...

Solar design triumphs through thick and thin The quest for high power-conversion efficiency in most thin-film solar cells has often been hindered by the “thick and thin” challenge, in which a cell must be thick enough to collect a sufficient amount of light, yet thin enough to extract current. Now a novel solar cell devised by physicists at Boston College in Chestnut Hill and inspired by the coaxial cable resolves this dilemma...

Photonics in South Korea and Singapore: People and places As is well known, South Korea is a high-tech industrialized nation and currently among the world’s 20 largest economies. Gwangju, its sixth largest city, was home to the World Photonics Expo 2010 in the spring and is the seat of the Korea Association for Photonics Industry Development (KAPID). The cluster organization in connection with industry, academia and government was founded to...

Playing “hide and seek” with warblers – and winning Birds are creatures of habit, and they tend to have certain features in mind when seeking out places to feed or to nest. Migratory birds, such as the black-throated blue warbler, leave their Caribbean and South American homes every year for new ones in the forests and groves of North America. Ornithologists trying to predict where these warbler populations might be found each year have been...
