摘要 根据掺铒光纤放大器(EDFA)的速率方程和传播方程,忽略自发辐射噪声,推导出了小信号调制时频率响应函数的解析表达式以及大信号调制时描述瞬态增益的方程。数值计算表明,当输入信号的调制频率大于5kHz时,放大器的瞬态增益变化很小,频率响应很弱。通过计算机仿真。 An analytical formula on small signal frequency response of Erbium doped fiber amplifier (EDFA) is deduced and gain modulation response for large signal modulation is investigated through numberical calculation. Computer simulations show that fast pump control can limit transient gain excursion of EDFA.
