Abstract

In this report, a theoretical model of in-band pumped holmium-doped silica fiber amplifiers (HDFAs) is presented. This model is developed to consider the influence of energy transfer up-conversion (ETU) on the HDFAs performance. The advantage of this model is to investigate the properties of HDFAs as a function of holmium-doped fiber length and doping concentration. A good agreement is observed between the simulation results and the previous experimental findings. Our simulation results show the negative impact of ETU process to deteriorate the HDFAs performance and this process may have bigger effect at high holmium doped concentration. This is the first time to our knowledge that the influence of upconversion process is theoretically investigated on the performance of in-band pumped HDFAs.

上转换过渡过程对带内泵浦掺-石英光纤放大器性能的影响

摘要

在这份报告中，提出了带内泵浦掺石英光纤放大器（HDFA）的理论模型。开发该模型是为了考虑能量转移上转换（ETU）对HDFA性能的影响。该模型的优点是研究HDFA的特性随掺-纤维长度和掺杂浓度的变化。在模拟结果和先前的实验结果之间观察到很好的一致性。我们的仿真结果表明，ETU工艺对HDFAs性能的负面影响，在高掺杂浓度下，该工艺可能会产生更大的影响。据我们所知，这是第一次从理论上研究上变频过程对带内泵浦HDFA性能的影响。
