摘要: 为了研究分组与线路集成系统中突发模式大功率Er/Yb共掺光纤放大器(EYDFA)的瞬态性能,在函数极限的基础上采用迭代算法,建立了基于非线性方程速率方程的、不同掺杂截面EYDFA增益瞬态的比较模型,分析比较了有/无反馈条件下,不同掺杂截面的光分组(OPS)和光线路交换(OCS)输出信号的增益瞬态.结果表明,无反馈条件下,纤芯直径为4.6m的EYDFA,其OPS和OCS输出信号功率漂移小于纤芯直径为3.6m的EYDFA,功率漂移的改善约为12%;带反馈条件下,增大掺杂光纤直径,弛豫振荡导致的EYDFA增益抖动随之减小.故增大掺杂光纤直径,能有效抑制EYDFA反馈环路的弛豫振荡.

Abstract: In order to investigate gain transient performance of burst-mode high-power Er/Yb co-doped fiber amplifier (EYDFA) in optical packet and circuit integrated network, comparison mode of gain transient performance of EYDFA with different doping area was proposed by adopting iterative algorithm of nonlinear rate-equations based on function limit. Gain transient performance of optical packet switching and optical circuit switching output signals with/without optical feedback , are analyzed and compared in detail. The results show that the maximum improvements of gain excursion for EYDFAs without optical feedback are about 12% when the core diameter of double-clad fiber changes from 3.6m to 4.6m. The gain fluctuation of EYDFAs with optical feedback caused by relaxation oscillation decreases with the increase of core diameter. The analysis suggests that relaxation oscillation of EYDFA feedback loop will be suppressed by enlarging active core diameter of doped fiber.
