Abstract: The guided to leaky mode conversion with the induced diffraction grating from the collinear surface acoustic wave (SAW) possess potential application in onboard optical demultiplexing of optic communication systems. This phenomenon is analyzed using the coupled mode theory. Mode conversion efficiency has been calculated as functions of acoustic frequency,interaction length,guiding layer thickness,and acoustic drive power density. It is shown that the x-cut configuration features the highest mode conversion efficiency,measured mode conversion efficiency as high as 90% is obtained at the relevant acoustic drive power density and interaction length.
