Abstract
A tangentially poled piezoelectric single crystal ring resonator is disclosed. A single crystal material is machined into elements and formed into a ring structure. The single crystal elements have a <110> poled tangential axis. The elements may also have a <211>, <511> or <322> orientation range in the radial direction. The elements may have a generally wedge shape.
