England Develops World's Fastest Optic Switch Breakthrough in High-SpeedCommunications

摘要

England's Gelasige University has successfully developed the world's fastestoptical switching device, allowing for a major breakthrough in high-speed communications. This switching device is called a non-linear direct coupler. It is a type of all-optical switch which operates with an extremely short strong laser pulse. The laser pulse is focused on a transistor waveguide and can change the optical properties of the transistor; thus by changing the laser pulse intensity, it is possible to change the light emitted by the transistor, thus changing the size of the switching pulse.
