Fabrication and Characterization of a High-Gain Yb-Er Codoped Phosphate Glass Optical Amplifier
Figure 4
Amplifier output spectrum of the Yb3+/Er3+ phosphate glass fiber obtained by exciting with a 479 mW pump at 975 nm and a 0 dBm signal at 1535 nm. The highest peak obtained at these conditions is shown (+6.714 dBm).
