Abstract :
A new advanced design methodology for multi/demultiplexers based on holographic concave gratings is presented. The proposed design is benchmarked against a single grating operating in the entire useful range of the single-mode fiber (1280-1680 nm). In addition, a new design for a grating serving as a 1000 wavelength-division-multiplexing channel demultiplexer within the 1450-1650 nm spectral range is given. It is shown that the new mount offers considerably improved performance.
