Summary:In this paper, we emphasize on the design and simulation of four channel, Photonic crystal Fiber(PCF) based arrayed waveguide (AWG) Demultiplexers for optical communication network. We have considered two types of AWG Demultiplexers, namely multicore and dual concentric core PCF.The simulation is performed for 1550nm central wavelength. The change in the effective index and dispersion is evaluated. The results show that dual concentric core PCF based AWG offers a dispersion of -4200 ps/nm/km dispersion and multicore PCF AWG offers -3500ps/nm/km dispersion, enabling the separation of wavelength. Finite difference time domain (FDTD) and Beam Propagation method is used for the analysis. The spectral response shows that the device has a wide free spectral range(FSR) sufficient enough to provide 100GHz Channel separation.
