Abstract :
We have demonstrated a high-performance Er3+/Ce3+ codoped tellurite fiber amplifier and tunable fiber laser using a dual-pumping scheme. The short 22-cm Er3+/Ce3+ ion codoped fiber exhibits a net gain of 28 dB at 1558 nm, a wide positive net gain bandwidth of 122 nm, and a noise figure of 4.1 dB. Finally, a widely tunable Er3+ /Ce3+ codoped tellurite fiber ring laser with a tuning range of 83 nm is demonstrated.
