摘　　要：在采用BPM法的基础上分析了玻璃波导中场的分布,提出了考虑增益后的光场数值模拟计算方法;比较了加入增益因子前后光场的变化,讨论了抽运功率、掺铒浓度及步长的变化对光场的影响,得到了场分布图。The field distribution of the gain glass waveguide is analyzed with beam propagation method (BMP),a numerical approach to calculate the field added gain gene is introduced.The variety of the field is discussed compared with the field added gain gene.The effects of pump power ,Er-doped concentration on the field are discussed particularly,the figurs of the field distributing are achieved.
