Scientists amplify light using sound on a silicon chip

摘要

Scientists at Yale University in the US have found a way to greatly boost the intensity of light waves on a silicon microchip using the power of sound. Writing in the journal Nature Photonics, a team led by Peter Rakich describes a new waveguide system that harnesses the ability to precisely control the interaction of light and sound waves. This work solves a long-standing problem of how to utilize this interaction in a robust manner on a silicon chip as the basis for powerful new signal-processing technologies.
