Paper Abstract

In this paper, the operation principle of the broadband Er-Tm co-doped silica fiber amplifier when pumped at 980nm is presented. Numerical analysis of this broadband Er-Tm co-doped silica fiber amplifier has been performed based on the rate and propagation equations. The signal amplification gain as functions of the fiber length, the input pump power, the erbium-thulium concentration, as well as the pumping ways is described. The results show that the erbium- thulium co-doped silica fiber amplifier could provide more than 80 nm effective gain bandwidth, which is twice larger than the conventional singly erbium-doped fiber amplifier. The minimum gain value exceeds 9 dB when the launched pump power is higher than 400 mW. These results could be useful for the optimized design of DWDM amplifier in the near future.
