Photonic Switch (1 of 2)

Caption

The photonic switch is built with more than 50,000 microscopic "light switches" etched into a silicon wafer. Each light switch (small raised squares) directs one of 240 tiny beams of light to either make a right turn when the switch is on, or to pass straight through when the switch is off.
