Abstract
An acousto-optic device having at least one groove on the backside improves acoustic termination of the device. The grooves can be added early in device fabrication and are compatible with batch processing, thereby avoiding the separate device handling. Grooving can be performed on the cell, before it is mounted to a batch plate. This simplifies batch plate processing by using a backside that remains parallel to the bondface.
