Abstract

Nonlinear chirped FBG(NLCFBG) is found to have the performance to compensate the dynamical nonlinear dispersion. In this paper, we investigate and compare, for the first time, the reflection spectrum and group delay of apodized nonlinear chirped fiber Bragg gratings which has raised much interest because of its reduced reflectivity sidelobes in dynamical status. The dispersion characteristics of apodized, nonlinearly chirped fiber Bragg gratings and their potential as dispersion compensators have been studied systematically. It is shown that the super-Gaussian profile and Cones function result in an overall superior performance, as it provides highly quadratic group-delay characteristics in the dispersion-slope compensation.
