Demonstration of on-chip gigahertz acousto-optic modulation at near-visible wavelengths

Lithium niobate integrated photonics has recently received significant attention because it exploits the attractive properties of lithium niobate on an integrated platform which provides strong optical confinement as well as high photonic integration density. Although many optical functionalities of...
