Abstract
The design, fabrication and evaluation of efficient wideband Bragg cells in gallium phosphide is reported. The devices were fabricated using the <110> and <111> longitudinal modes of acoustic propagation with design bandwidths of 500 MHz centred on 1.2 GHz. State-of-the-art efficiencies of up to 115%/W and 220%/W, respectively, were obtained.
