Researchers Build Exciton-Based Devices Alexander E. Braun, Senior Editor - 09/22/2008
By using excitons, i.e. particles that emit photons as they decay, it may be possible to produce a new form of computing, better suited to fast communications. University of California at San Diego Professor Leonid Butov has built exciton-based transistors and the first computing devices to use excitons. More
Carl Zeiss Invests in 3-D Nanostructuring Startup Nanoscribe Staff - 10/01/2008
Carl Zeiss has acquired a stake in Nanoscribe (Karlsruhe, Germany), a startup that recently fielded its laser direct-write tool for 3-D nanostructuring. 3-D laser lithography is applied in developing prototypes of micro and nanophotonic devices, among other applications.

Brazilian ‘Photonic Beetle’ Points Way to Ultrafast Computing Alexander E. Braun, Senior Editor - 09/08/2008
Scientists have discovered that their research to build photonic crystals was redundant — Mother Nature had already produced them with the ideal diamond-like structure, to decorate a beetle’s carapace.
