ABSTRACT:
To provide electrical isolation to piezoelectric parallel shear mode elements in wavefront phase modulators arrays, the functionality of the mounting configuration is increased. The mounting configuration involves embedding a respective interface electrode affixed to a second face of each piezoelectric element of the array in an insulating ridge. This allows the ridge to provide electrical isolation to interface electrodes affixed to adjacent elements. A first surface of every element is electrically connected to a common potential source by a suitable means. Electrically connecting the first surface of every adjacent element in the array to a common potential source avoids electrical interference between adjacent elements. By increasing the functionality of the ridges and making judicious use of common potential interconnects between adjacent elements, extraneous components, such as electrical insulators can be eliminated. This facilitates implementation of piezoelectric wavefront phase modulator arrays.
