依据掺铒光纤放大器的速率方程和光传输方程,在不计放大自发辐射的情况下,得出了抽运功率和信号增益在放大器中沿光纤分布的隐函形式的解析表达式,并利用数值模拟对三种抽运方式下的放大器特性进行了分析。
According to the rate equation and optical transmission equation of erbium-doped fiber amplifier, the analytic expression of the implicit form of pumping power and signal gain along the optical fiber in the amplifier is deduced without considering the amplification of spontaneous emission. The numerical simulation of The characteristics of the amplifier under three pump modes were analyzed.
