In developing new layouts for multiplexer/demultiplexers (mux/demuxes) with diffraction gratings (DGs), the problem arises of choosing the optimum design. A technique is proposed that makes it possible to analyze the efficiency of versions of mux/demuxes based on flat and concave DGs. The results of a calculation of the efficiency of single-mode ten-channel mux/demuxes with a concave DG (CDG) in the spectral region 1.24-1.33 µm are presented. The results of a calculation of the efficiency of mux/demuxes with flat and concave gratings are compared on the region 1.53-1.57 µm.
