Infrared light passes through silicon the way visible light passes through glass. Just as a prism bends visible light to reveal the rainbow, different silicon structures can bend infrared light in useful ways. It is theoretically possible to replace wires with silicon fibers. Why bother: to transmit lots more data while using lots less energy.
