Light and sound in silicon chips: The slower the better

ScienceDaily.com: Nanotechnology News - Mon, 09/16/2019 - 16:14
Acoustics is a missing dimension in silicon chips because acoustics can complete specific tasks that are difficult to do with electronics and optics alone. For the first time researchers have added this dimension to the standard silicon photonics platform. The concept combines the communication and bandwidth offered by light with the selective processing of sound waves.
