Optimum Apodization Profile for Chirped Fiber Bragg Gratings based Chromatic Dispersion Compensator

Abstract

In this paper, we optimize the apodization profile to improve the dispersion compensation performance of the chirped fiber Bragg gratings (CFBGs). Tanh, Exponential, and Hamming apodization profiles were evaluated at 2000 nm wavelength. Our aim is to obtain the minimum average group delay ripple (GDR) and maximum FWHM bandwidth. The result shows that the best FWHM bandwidth is obtained by using Tanh profile that is approximately 96.27%. No significant difference can be observed in the GDR.
