for fiber-optical communication systems are reviewed with respect to technology, fiber coupling, and device configurations. Typical devices for communication applications, such as modulators/switches, multiplexers, switch arrays, and heterodyne receiver chips rely on electrooptically controlled waveguide structures. Their operation mechanisms and performance characteristics are described to highlight the present status of development and of system applications.
