Abstract
It is well known that a ZnO-on-Si structure supports two distinct surface waves, called the Rayleigh and the Sezawa modes, if the ZnO layer is sufficiently thick. Herein we report a unique surface wave resonator that operates by efficiently converting between the two modes at the resonant frequency. The mode conversion resonator promises enhanced out-of-band signal rejection since input and output coupling is effected through different modes.Keywords
