Additionally, a lot of research has been done to use SAWs in quantum technologies like quantum transduction. In this thesis, Young’s double-slit experiment has been carried out using SAWs on anisotropic gallium arsenide with the goal of comparing the results to the existing scalar optical diffraction theory. Simulations have been made based on the mentioned theory and the measurements have been done using a Michelson interferometer with lock-in detection. Despite non-ideal samples, the diffraction and interference of SAWs have been observed. The experimental data agrees somewhat with the simulations taking into account the anisotropic wave speed. We have also measured the angular phase velocity relation of gallium arsenide and found it to be consistent with the literature.Show less
