Abstract

A review is presented of state-of-the-art optical planar waveguide demultiplexers (DEMUXes); that is, phasars (arrayed waveguide) and etched grating devices designed for high density (narrow channel spacing) wavelength division multiplexing (WDM) systems. Their advantages and disadvantages are discussed in comparison with other techniques for demultiplexing WDM signals. The advances made in their performance are reviewed and ultimate limitations, set by technological constraints, are proposed. Finally, a comparison is made of the advantages and disadvantages of etched grating as opposed to phasar planar waveguide DEMUXes.
