Abstract

We present a numerical model of an Er 3 + - Tm 3 + - Pr 3 + codoped fiber amplifier pumped with an 800 nm laser for the first time to the best of our knowledge. The rate and power propagation equations are solved numerically, and the dependence of the gains at 1310, 1470, and 1530 nm windows on the active ion concentrations and fiber length are calculated. The results show that with pump power of 20 mW , when Pr 3 + - Tm 3 + - Er 3 + concentrations are around 2.0 × 10 24 , 2.0 × 10 24 , and 2.26 × 10 24 ( ions / m 3 ), respectively, the signals at 1310, 1470, and 1530 nm windows may be equally amplified in the active fiber with a length of 1.3 m .
