A proof-of-concept device that could pave the way for on-chip optical quantum networks has been created by a group of researchers from the US. Presenting the device today, 8 February, in the Institute of Physics and German Physical Society's New Journal of Physics, it has been described as the "building block of future quantum networks." In an optical quantum network, information is carried between points by photons — the basic unit of light. There is a huge potential for this...

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...

Silicon microring resonator could help advance nanomanipulation To trap and hold tiny microparticles, engineers at Harvard have "put a ring on it," using a silicon-based circular resonator to confine particles stably for up to several minutes. The advance, published in the June 14 issue of Nano Letters, could one day lead to the ability to direct, deliver, and store nanoparticles and biomolecules on all-optical chips. "We demonstrated the power of what we call resonant cavity trapping, where...

With a bit of leverage, Cornell researchers have used a very tiny beam of light with as little as 1 milliwatt of power to move a silicon structure up to 12 nanometers. That's enough to completely switch the optical properties of the structure from opaque to transparent, they reported. The technology could have applications in the design of micro-electromechanical systems (MEMS) -- nanoscale devices with moving parts -- and micro-optomechanical systems (MOMS) which combine moving parts with...
