Abstract:The optical communication is developing at very fast speed these years.Wavelength Division Multiplexing (WDM) is an effective technique to meet the fast-grown demand for communication capacity.Dense Wavelength Division Multiplexing (DWDM) has been successfully put into commercial use.DWDM′s ability of expanding the communication capacity is in continuous growth.As the key device of a DWDM system,Etching Diffraction Grating (EDG) is one of the most potential types of planar waveguide DWDM devices.In this paper a brief introduction of EDG is presented,the design of the EDG parameters is analyzed and the manufacture process is described.A simple model for the simulation of EDG is introduced and the basic demultiplexing characteristics of EDG is obtained.Numerical results for the intensity distribution along the output,the spectral response and the dispersion are given and analyzed.
Keywords:Planar waveguide  Dense wavelength division multiplexing  Rowland circle  Etched diffraction grating
