Silica Optical Fiber Technology for Devices and Components: Design, Fabrication, and International Standards

As the emphasis in optical fiber research expands from transmission media to functional fiber devices, various types of specialty optical fibers are being actively developed. Especially in dense wavelength multiplexing (DWDM) systems, novel functions such as fiber filters, fiber MUX/DEMUX, fiber amplifiers, among others, are constantly needed and supplied by specialty fibers. Until recently, optical fibers were treated as passive transmission media with very little attention given to these novel fiber technologies.
