Abstract
This paper elaborates on how the finite element method is employed to model surface
acoustic waves generated by high aspect ratio electrodes and their interaction with optical
waves in a waveguide. With a periodic model it is shown that these electrodes act
as a mechanical resonator which slows down the SAWvelocity because of mechanical
energy storage. A finite model is furthermore employed to study the acousto-optical
interaction and shows that it is possible to get a bigger change in effective refractive
index with these surface acoustic waves compared to using conventional interdigital
transducers. Thus, this indicates a way to improve acousto-optical interaction.
