Abstract:

Thulium doped optical amplifier is the optical amplification solution for the S-band (1460−1530 nm). In this paper, the ZrF4-BaF2-LaF3-AlF3-NaF based Thulium doped optical amplifier for S-band optical amplification is studied for observing the effect of variation in doping radius and doping concentration on the gain. Also, the scenarios with 1050 nm and 1050 nm + 1400 nm + 800 nm pumping are analyzed. The doping concentration is varied in the range of 20×1024 m−3 to 80×1024 m−3, and doping radius is varied in the range of 0.3 μm to 1.3 μm. From the obtained results, it has been observed that the doping parameters have a significant effect on the gain of Thulium doped optical amplifier. The peak gain of 30.5 dB is observed for the 1050 nm + 1400 nm + 800 nm pumping of the Thulium doped optical amplifier having a doping concentration of 40×1024 m−3 and doping radius of 0.9 μm.
