| 摘 要： | 控制激光的弛豫振荡和空间烧孔现象的存在 ,对全光增益控制掺铒光纤放大器 (EDFA)的性能产生劣化影响。采用一种新颖简单的利用两对光纤光栅对形成谐振腔结构 ,实现双波长增益控制掺铒光纤放大器。由两个不同波长的激光共同承担增益控制的任务 ,降低了控制激光引起的空间烧孔现象和瞬态输出变化。在动态工作条件下 ,双波长激光增益控制掺铒光纤放大器显示出优越的特性 ,适用范围扩展为普通单波长增益控制掺铒光纤放大器的两倍 ,能够适应 0～ 43kHz的上下载频率。 |

| Abstract: | A simple configure for automatic gain control of optical amplifiers is presented, in which two pairs of FBGs are used to form dual-oscillating lasers. The experimental results suggest that the configure can be employed to significantly reduce surviving channel steady-state and transient power excursion. Moreover, the effects of the gain control EDFA on surviving channel at different add/drop frequency are discussed. Experimental results show that the dual-oscillating laser gain controlled EDFA operates satisfactory with channel′s add/drop frequency up to 43 kHz which is significantly higher than that with single-oscillating laser control. |
