High‐Efficiency Acousto‐Optic Modulation on Non‐Suspended Thin‐Film Lithium Tantalate

ABSTRACT Acousto‐optic (AO) interactions provide a powerful interface between the microwave and optical domains, enabling optical switching, non‐reciprocal propagation, and efficient microwave‐to‐optical transduction. Here, we demonstrate high‐efficiency AO modulation on a non‐su...
