Part of the Springer Series in Photonics book series (PHOTONICS, volume 1)


This chapter is dedicated to integrated or fiber devices which multiplex or demultiplex optical signals in wavelength, time or polarization. The need for signal multiplexing/demultiplexing had appeared from the necessity to increase the amount of information which can simultaneously be transmitted from a source to a receptor. In order to do this the different information channels must be separately identifiable — they must differ in wavelength, time sequence or polarization. At the same time, they should be transmitted simultaneously — generally through an optical fiber. The devices which combine and separate (multiplex and demultiplex) different information channels will be presented in the following.
