Design of Optical Demultiplexer using Arrayed Waveguide Grating

Abstract-- Optical demultiplexers are used to receive multiple frequency signal from an optical fiber and to split it into its different frequency components. Arrayed waveguide gratings can be used to design an optical demultiplexer and works on the principle of interferometry. This paper presents the design of optical demultiplexer for an optical signal composed of eight frequency components. Simulation results have been presented
