Analysis of the Apodization Parameter of Linearly Chirped Bragg Gratings for Dispersion Compensation

In this paper, a system model that compensates the dispersion of 100 km of standard single-mode fiber is designed, the effect of different apodization sharpness on the spectral response is compared. It is demonstrated that the apodization sharpness parameter plays a more important role in the behavior of the mean dispersion, group delay ripple and some other spectral responses even than the type of apodization profile itself. It is also shown that an apodization parameter about 0.7 results in better spectral response as minimum group delay ripple impact, minimum deviation from the required dispersion value and so on. The results of this analysis can be used as a reference for further studies of apodized linearly chirped fiber Bragg gratings.
