Abstract

Grating based integrated waveguide demultiplexer is one of the most promising types of planar waveguide DWDM devices. In order to reduce reflection loss of the grating, the grating facets need metallic coating for high efficiency. The analysis of retro-diffraction efficiency for echelle grating with metallic coating is given in the present paper by using a Finite-Difference Time-Domain (FDTD) method. This numerical method is more accurate and reliable than other methods such as the ray approximation method. Numerical simulation is given for S-polarized lights and the numerical results show that the loss is about 1dB.
