Abstract
This chapter discusses research, development, and education on wavelength-division multiplexing (WDM) technologies. Multiplexers (MUX)/Demultiplexers (DMUX) are the key optical passive components that have revolutionized the optical network, extending its horizon from core to edge. These components play a key role in realizing all optical networks. This part covers the integrated router made from planar lightwave circuit (PLC) technology, and also discrete MUX/DEMUX and circulator, frequently used in the optical networks. The design, fabrication, and performance of the arrayed waveguide grating (AWG) based on the PLC technologies are analyzed. Optical switches are the key components that provide bandwidth management, ring interconnect, protection, or mesh restoration in the optical layer. The different kinds of optical switches based on the electromechanical, thermo-optic, and electro-optic effects for the applications to optical networks are presented. The development of guided-wave optical switch technology using an electro-optic material, especially LiNbOs, substrate is reviewed. The state-of-the-art future functional devices, fabricated monolithically on the single wafer, based on compound semiconductors are also elaborated.
