Abstract

An intersecting wave guide has a high extinction ratio, low loss, and wavelength independent characteristics for an acousto-optic tunable filters (AOTF). An oxide film-loaded surface acoustical wave guide (SAWG) has a strong confinement, excellent filter characteristics, and provide high design flexibility. In this paper we present a numerical method for an oxide film-loaded SAWG on a substrate. The result is agreed with the experiment.
