Performance comparison of Fiber Bragg Grating for different Grating length, Apodization function and Chirp function

Optical communication has emerged as one of the most significant way of communication in the recent years due to its wide available bandwidth, faster data rate and cost effectiveness. But factors like attenuation, dispersion, non-linearities limits the performance of optical communication network. This paper investigates the effect of dispersion on optical communication and how to mitigate it using suitable dispersion compensation techniques. Here Fiber Bragg grating is used as an effective dispersion compensation method. Further the properties of the FBG like Grating length, Apodization function and Chirp function are varied to obtain best possible results. The results obtained are compared in terms of Q Factor and Bit error rate. The entire simulation is done using optisystem 14 software.
