Design of Different Demultiplexers for Wavelength Division Multiplexing Systems Based On Photonic Crystal Waveguide

Dinesh Bhatia, Nikhil Deep Gupta

Waveguides made up of photonic crystals have some unique properties such as air core guidance with band gap effect, effective refractive index guidance etc. These unique properties have their direct dependence on the degree of freedom associated with photonic crystals. This degree of freedom allows us to use these waveguides as de-multiplexers by creating defects within the waveguides. The work is concerned about the design and simulation of different de-multiplexers based on photonic crystal waveguide by creating different types of defects within the waveguide.
