Numerical Simulation of 980 nm-LD-Pumped Yb3+-Er3+-Tm3+-Codoped Fiber Amplifier for 1500 nm and 1600 nm Bands
Figure 4
Dependence of the gain spectra with fiber length, the concentrations of Yb3+, Er3+, Yb3+, ion are 20.0 × 1024, 1.0 × 1024, 3.0 × 1024 ions/m3, respectively, and pump power, and input signal power are 200 mW, 30 dBm, respectively.
