redOrbit Staff & Wire Reports - Your Universe Online Scientists at the University of Minnesota have invented a unique microscale optical device that could dramatically increase download speeds while lowering bandwidth costs. The device uses the force generated by light to rapidly turn a mechanical switch of light on and off, a breakthrough that offers advances in computation and signal processing using light instead of electrical current – offering greater performance and lower...

As researchers push towards detection of single molecules, single electron spins and the smallest amounts of mass and movement, Yale researchers have demonstrated silicon-based nanocantilevers, smaller than the wavelength of light, that operate on photonic principles eliminating the need for electric transducers and expensive laser setups.The work reported in an April 26 advance online publication of Nature Nanotechnology ushers in a new generation of tools for ultra-sensitive measurements at...
