“…The use of a linear passive edge filter is very critical for wavelength measurements in multichannel Dense wavelength division multiplexing optical communication systems and FBG-based optical detection systems. 15 A linearly sloped region is created to detect the wavelength change by a passive edge filter. When the wavelength of the reflected light signal changes in this sloped region, the optical density of the light also changes.…”

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° was obtained.
