Abstract

This work is novel in that it explains the modeling and simulation of a thulium-doped fiber amplifier (TDFA) in a reconfigurable wavelength division multiplexing communication system operating at 2 μm. We use the optical gain-clamping technique in order to control gain amplification and reduce delet...
