采用平均反转率模型分析了带光纤布喇格光栅的增益平坦掺铒光纤放大器 ,其输出增益可由一组耦合超越方程描述 ,而非耦合微分方程 ,同时讨论了用于增益平坦的布喇格光栅的最佳位置设计 作为增益建模和最佳设计实例 ,对于输入功率 0 .5mW位于 1 5 4 5～ 1 5 5 2nm的 8个波长信道 ,得到的输出增益不平坦度小于 0 .0 5dB .最后还证实了布喇格光栅作为增益均衡器具有高输出功率和功率转换效率的优越性
The average gain model is used to analyze the gain - flattened erbium - doped fiber amplifiers with fiber Bragg gratings. The output gain can be described by a set of coupled transcendental equations rather than coupled differential equations. The Bragg The best position of the grating design as a gain modeling and best design example, for the input power of 0 .5mW located at 1 5 4 5 ~ 1 5 5 2nm 8 wavelength channels, the resulting output gain unevenness is less than 0 0 5dB Finally, it confirms the superiority of Bragg grating as a gain equalizer with high output power and power conversion efficiency
