This optical switch is super small and crazy fast

A new optical switch can turn on and off trillions of times a second–and it’s remarkably small.

The device consists of individual switches that are only one five-hundredth the width of a human hair (200 nanometers) in diameter. This size is much smaller than the current generation of optical switches and it easily 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.
