Abstract

In this study, passive edge filter design was implemented by using I-6, I-25, M-5, M-12 erbium-doped fibers. For this purpose, first the highest bandwidth and the steepest slope regions of the erbium-doped fibers were determined in the simulation environment. The experimental setup was realized by using the most appropriate lengths of erbium-doped fibers found in the simulation study. For I-25 erbium-doped fiber, an edge filter with a bandwidth of 32.8 nm and a slope angle of 50.77 degrees was obtained.
