New research out of MIT could lead to smarter airport scanners able to detect the presence of drugs and explosives. At the heart of the development is a new approach to laser tuning designed to harness terahertz rays so that they can be used to determine an object's chemical composition.  Read More

The first commercial shipment of low-light, ultra thin, solar cell technology called DSSC,...

The first commercial shipment of low-light, ultra thin, solar cell technology called DSSC (dye-sensitized solar cells), created by G24 Innovations, has been sent to Hong Kong-based consumer electronics bag manufacturer, Mascotte Industrial Associates for use in backpacks and bags. Ideal for clothing and portable applications, DSSCs are less than 1mm thick, inexpensive, don’t contain silicon or cadmium and can even operate indoors, making them ideal for powering cell telephones, cameras and portable electronics. The company says DSSCs also can be embedded into tent material to power LED lighting systems for camping.  Read More

Excitonics could provide us with faster computers and better communication speeds - except...

Much of today's research in electronics is geared towards obtaining faster computing and higher communication speeds. Researchers at UC San Diego are no exception, and have recently announced they have made another important step towards achieving exciton-based computation at room temperatures. Excitonics exploits the unique properties of excitons instead of the usual electrons, and promises much faster performance by interfacing more naturally with optical communications such as fiber optics.  Read More

Researchers at Cornell, Purdue and Norfolk State University have reported the successful creation of a 'spaser', a new kind of nanoscale laser that breaks dimensional limits previously thought to be insurmountable, leading the way to significantly faster and more efficient computer processing and data transfer rates.  Read More

Scientists are rapidly achieving important breakthroughs in quantum computing, from obtaining precise manipulation of four photons at the same time to the very first quantum processors. But just like in traditional electronics, a quantum computer can't be realized with information processing alone — we need a reliable way to store and retrieve quantum information too. A new breakthrough by MIT researchers represents a step forward in acheiving this goal of high-fidelity quantum memory.  Read More

Quantum photonics is a particularly attractive field to scientists and engineers alike in that it could, once some core issues have been resolved, allow for the production of integrated circuits that operate on the basis of photons instead of electrons, which would in turn enable considerably higher data transfer rates as well as dramatically reduced heat dissipation. Now in yet another important achievement on the road to quantum computing, researchers from ETH Zurich have managed to create an optical transistor from a single molecule.  Read More

Australian researchers estimate that nanotechnology can boost DVD storage 2000-fold, witho...

Until recently, the idea of holding your entire collection of movies on a single super-sized DVD was the stuff of science fiction. According to Australian researchers at Melbourne's Swinburne University of Technology, advances in their study of nanoparticles have raised the possibility of storing vast amounts of data on the one disc in the not-too-distant future.  Read More

Internet speeds of a terabit per second have come one step closer with scientists at the University of Sydney developing a photonic integrated circuit (PIC) that can not only increase internet speeds by 60 times, but can also act as traffic monitors to keep the speed high and error free.  Read More

Miniaturized color MEMS scanning mirror-based Laser Projector

May 31, 2007 The collective intelligence of the world’s technologists seems destined to give us the miniature projectors we’ve been promised for so long that will likely revolutionise personal infotainment in mobile devices, the automotive industry (driver assistance, Head-Up Display, etc), medical electronics (acquisition of biometrical data, positioning aid for X-Ray diagnosis and treatment etc), production technology (projection of reference points for drilling, pattern generator for tailoring of steel plates), and Metrology (structured lighting). Earlier this week we reported on the XXXX and now comes the news that a full color laser projection system based on a two dimensional micro scanning mirror technology will be shown at at the LASER 2007 show in Germany next month. The system contains an ultra compact projection head and a separate laser and signal processing unit. It allows the projection of arbitrary images and video sequences with a geometrical resolution of 640 x 480 pixels, 256 brightness levels per pixel and elementary color, and 50 hertz frame rate.  Read More
