Two Dimensional Photonic Crystal based Four Channel Demultiplexer for ITU.T.G 694.2 CWDM Systems
نویسنده
چکیده
In this paper, four channel demultiplexer is designed using two-dimensional photonic crystal for Coarse Wavelength Division Multiplexing applications. The proposed demultiplexer consists of bus wave guide, output wave guide and a cavity. The channel selection is done by having a cavity with unique refractive index. The two dimensional finite difference time domain and plane wave expansion methods are employed to estimate the normalized spectrum and band gap of the proposed demultiplexer. The footprint of the proposed demultiplexer is about 129.96μm 2 which is very small and hence it is suitable for Photonic Integrated circuits.
