Abstract

Delay characteristics of cascaded chirped fiber Bragg gratings (CFBGs) have been theoretically analyzed. Delay ripple increases while the number of cascaded CFBGs increases, and also increases as the wavelength interval between neighbor CFBGs decreases. A way to mitigate the effect, namely using 8-order Gaussian apodization when CFBGs are written is found.
