Periodically poled LiNbO3 transducer on (YXl)/128° cut for RF applications

Previous studies have shown Periodically Poled Lithium Niobate structures on Z-cut LiNbO₃ could be used as acoustic transducers to generate acoustic waves. Investigations on Periodically Poled LiNbO₃ (YXl)/128° transducers have been conducted. Simulations have pointed out interesting electromechanical coupling from such transducers. Fabrication of Periodically Poled (YXl)/128° LiNbO₃ transducers bonded/thinned on Silicon is presented and confirm the possibilities of rotated cuts poling for new transducers.
