Ultra-Wideband and Low DMG Four-Mode-Group TDFA Based on Hybrid-Mode Pumping (W2A.28)

Presenter: Chaoya Shan, Beijing University of Posts and Telecomm

We propose a four-mode-group thulium-doped fiber amplifier (TDFA) operating within the 1720-2000 nm waveband with a differential mode gain (DMG) below 3.7 dB by implementing hybrid-mode pumping scheme and particle swarm optimization.
