用重合积分的方法 ,分析了描述掺铒光波导放大器 (EDWA)的速率方程 ,得到了 980nm波段抽运的掺铒光波导放大器增益的隐式解析解 ,在此基础上得到了抽运阈值功率的解析表达式。计算了掺铒平面光波导放大器中的光场与铒掺杂浓度分布的重叠因子。讨论了铒掺杂浓度对抽运阈值功率的影响及抽运功率对增益的影响。
The coincidence integral method is used to analyze the rate equation of EDWA. The implicit analytical solution of the gain of erbium - doped waveguide amplifier pumping in 980nm band is obtained. Based on this, the pump threshold power Analytic expression. The overlap factor between the optical field and the erbium doping concentration distribution in the erbium-doped planar waveguide amplifier was calculated. The influence of erbium doping concentration on pumping threshold power and pumping power on gain are discussed.
