Optical switch development cuts power consumption by half

Fujitsu Laboratories has unveiled a new optical switch technology that it claims uses half the power of conventional optical switches. The new optical waveguide switch uses photonics made from silicon germanium (SiGe) instead of pure-silicon semiconductor material. This technology will be the basis for a new generation of high-speed optical switches capable of operating across a wide range of wavelengths, while featuring perhaps the world’s lowest power requirements.
