摘要
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 rate equations for integrated erbium-doped waveguide amplifiers (EDWA′s) pumped at 980 nm wavelength are analyzed using overlapping factors methods. An analytical implicit gain solution of EDWA′s is derived. Based on which an analytical threshold expression of pumping power is obtained, and overlapping factors between the erbium concentration and the pumping and signal light field intensity distribution inside the erbium-doped planar optical waveguide amplifiers are calculated. The effect of erbium-doped concentration on pump threshold power and the effect of pump power on gain are discussed.
