Semiconductor Optical Integrated Functional Devices for Advanced Optical Communication Networks

Abstract

Optical cross connects and optical add-drop multiplexers are expected to be key technologies to realize higher reliability and flexibility in future optical communication networks, where a huge amount of informations are transmitted over many fibers and many wavelengths. Recent progress of semiconductor optical integrated functional devices are reviewed with emphasis on optical matrix switches, semiconductor arrayed waveguide gratings and their combinations from view points of applications to optical cross connects and optical add-drop multiplexers.
