Abstract
In this paper, we present a novel method for the fabrication of an EDFA gain flattening filter(GFF) with two identical chirped fiber gratings formed in series after a double exposure. This method shows a significant improvement in the flattening level and error function in GFF, compared with the conventional method for forming the OFF by using single chirped fiber grating for equalizing the gain spectrum.
