RESEARCH AND DEVELOPMENT
University researchers have invented an ultrafast and ultrasmall optical switch that could advance the day when photons replace electrons in the internal circuitry of consumer products ranging from cellphones to automobiles. The new optical device can turn on and off trillions of times per second. It consists of individual switches that are only one five-hundredth of the width of a human hair (200 nanometers) in diameter.
The device is much smaller than the current generation of optical switches, and it breaks one of the major technical barriers to the spread of electronic devices that detect and control light: miniaturizing the size of ultrafast optical switches.
