Paper Abstract

A new technique is developed for improved efficiency with planar phased array Bragg cells. By the preparation of a groved substrate surface prior to the fabrication of a planar phased array acoustic transducer, the symmetry of the planar phased array structure is removed, As a result, one of the two acoustic first order wavefronts can be suppressed. Bragg diffraction efficiency is improved by approximately a factor of two due to the concentration of acoustic power. Several devices have been fabricated successfully on GaP substrate demonstrating the expected efficiency gain.
