Wavelength Division Multiplexing/Demultiplexing (WDM) Using Diffraction Gratings

J. P. Laude, Jeremy M. Lerner

Abstract

This paper reviews the present status of diffraction grating based wavelength division multiplexer/demultiplexers (WDM). A comparison is made of WDM's currently in commercial use with both monomode and multimode fibres. Devices are described ranging from an industrial system multiplexing and demultiplexing 49 channels to a 12-channel monomode demultiplexer. The discussion includes multi-multiplexers in which several multiplexers share a common optical element.
