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 20ґ1024 m-3 to 80ґ1024  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 40ґ1024 m-3 and doping radius of 0.9 µm.

Keywords: ZrF4-BaF2-LaF3-AlF3-NaF, Thulium doped optical amplifier, S-band, gain.

Исследование влияния изменения параметров активатора на усиление туллиевого волоконного усилителя

© 2021 г. Rajandeep Singh, Maninder Lal Singh

Волоконные туллиевые оптические усилители (англ. TDFA) широко применяются для работы в диапазоне длин волн (1460-1530) нм (S-полоса). Исследован эффект изменения усиления активированного туллиевого волокна на основе ZrF4-BaF2-LaF3-AlF3-NaF (ZBLAN) при изменении радиуса и концентрации активатора. Проанализированы эффекты, связаные с изменениями условий накачки на длинах волн 1050 нм и (1050 + 1400 + 800) нм, соответственно. Вариации концентраций активатора находились в пределах (20-80)ґ1024 м-3, а радиусов — (0,3-1,3) мкм. Показано существенное изменения усиления Tm-ZBLAN усилителей при изменении указанных параметров. Пиковое значение усиления в 30,5 дБ наблюдалось при накачке (1050 + 1400 + 800) нм для концентрации  40ґ1024 м-3 и значении величины радиуса 0,9 мкм.

Ключевые слова: ZBLAN, туллиевый оптический волоконый усилитель, S-полоса, усиление.
