World’s fastest nanoscale photonics switch

Researchers developed an ultrafast all-optical switch based on nonlinear dielectric silicon nanostructures. The operation of the switching is based on the interaction between two femtosecond pulses; at the same time, the undesirable free-carrier effects are suppressed. Ultrafast optical switching will permit to create data transmission and processing devices which will handle speeds high enough to download thousands of HD-movies in a second. —> Read More
