A MoM-based design and simulation method for an etched diffraction grating demultiplexer

• A design and simulation method based on the method of moment (MoM) is proposed for an etched diffraction grating (EDG) demultiplexer. The method of moment is used to calculate the surface current, which produces the diffracted field at the image plane, for both polarizations. The present method can be used to design and simulate effectively and accurately an EDG demultiplexer with required specifications (such as the chromatic dispersion and loss variation) for both polarizations and the polarization-dependent loss.
