The acousto-optic properties of a double-core optical fiber are numerically investigated. The behavior of the power propagation, the transmission spectrum and the acoustically induced strain in the fiber is simulated using the 3D finite element method. The results indicate a promising first approach for the design of acousto-optic devices in complex fiber geometries.
