Abstract
Diffraction of laser light from bulk waves present in a LiNbO3 surface wave delay line has been used to probe surface wave mode conversion. Up to 4% of the power present in a surface wave incident on a reactively loaded interdigital transducer has been observed to be scattered into shear waves. In addition, a driven interdigital transducer has been seen to radiate bulk waves with directivity properties well described by a phased array antenna model.Keywords
