Silicon chips combine light and ultrasound for better signal processing

High-end wireless and cellular networks rely on light for the distribution of signals. The selective processing of such signals requires long delays: too long to support on a chip using light alone. A research team brought together light and ultrasonic waves to realize ultra-narrow filters of microwave signals, in silicon integrated circuits. The concept allows large freedom for filters design.
