研制了一种新型掺铒碲酸盐玻璃TeO2-ZnO-Na2O-Bi2O3,利用Judd-Ofelt和McCumber理论计算了Er3+离子的强度参数、自发辐射几率、吸收截面和发射截面等光谱参数.应用四能级粒子数速率-光功率传输方程模型,研究了以该掺铒碲酸盐玻璃光纤作为增益介质时光纤放大器的增益特性,模型综合考虑了Er3+离子的能量上转移、交叉驰豫、激发态吸收和放大自发辐射噪声.模拟结果显示,研制的碲酸盐玻璃光纤具有高的信号增益和宽的增益谱特性,在200 mW泵浦功率和多波长信号(-30 dBm× 56 channels)同时输入情形下,最大信号增益和20 dB增益带宽分别超过了40 dB和80 nm,增益谱覆盖了C+L波段区域,预示这是一种较为理想的可用于宽带放大的增益介质.同时得出,碲酸盐玻璃光纤结构参数的选择对其增益特性具有重要影响.
