Free-space coupling and characterization of transverse bulk phonon modes in lithium niobate in a quantum acoustic device
J. M. Kitzman, J. R. Lane, C. Undershute +5
Transverse bulk phonons in a multimode integrated quantum acoustic device are excited and characterized via their free-space coupling to a three-dimensional (3D) microwave cavity.…
