Domain inverted acousto- and electrooptic devices and their application to optical communication, sensing, laser sources, and quantum key distribution

The current status of domain inverted lithium niobate acousto- and electrooptic devices is reviewed. We introduce the main domain microengineering techniques and their impact on modulators’ performance in terms of reduced power consumption and enablers for a new class of integrated devices. We will then review potential applications of the devices in increasingly important areas, such as advanced optical communication modulation formats, reconfigurable networks, sensors and quantum key distribution.
