Wideband and flat gain series erbium doped fiber amplifier using hybrid active fiber with backward pumping distribution technique
A modern wideband and flat gain erbium-doped fiber amplifier (EDFA) is suggested and accomplished, by employing a recently fabricated hafnia-bismuth-erbium doped fiber (HB-EDF) and zirconia-erbium doped fiber (Zr-EDF) as a hybrid active fiber. The performance of the proposed EDFA is examined in both forwa...

| Summary: | A modern wideband and flat gain erbium-doped fiber amplifier (EDFA) is suggested and accomplished, by employing a recently fabricated hafnia-bismuth-erbium doped fiber (HB-EDF) and zirconia-erbium doped fiber (Zr-EDF) as a hybrid active fiber. The performance of the proposed EDFA is examined in both forward and backward pumping schemes, using 0.5m long HB-EDF and 4m long Zr-EDF in series structure to fulfill a wideband amplification that cover C- and L-telecommunication bands, respectively. At the optimumlaser diodes powers, the backward pumping amplifier attained a gain flatness of 14.6dB with the maximum gain variation of±1.8dB, throughout a wide bandwidth of 70nm, that is from 1530nm to 1600nm. The noise figure fluctuates from 4.3dB to 7.9dB within the gain flatness band. Using the backward pumping distribution technique, the proposed amplifier demonstrates not only an efficient performance, but also a cost reduction since only one laser diode is utilized to pump two stages. |
