半导体光放大器自动增益控制的实验研究
Experiment Study of Traveling-Wave Semiconductor laser Amplifier Automatic Gain Control
摘要
从行波半导体光放大器(TW-SLA)的增益特性出发,对光放大器的自动增益控制(AGC)进行了研究,设计出一种全电子自动增益控制系统.自动增益控制系统对光放大器输出功率的波动有明显的改善作用,能够对由于工作温度、输入偏振态的变化而产生的光放大器增益变化进行自动控制,并对前级输入光功率的波动进行调节.
Abstract
This peper studies the. traveling-wave semiconductor laser amplifier (TW-SLA) automatic gain control (AGC) technique which provides compensation for varistions in amplifier gain caused by the environmental effects and changes in system variables. Theoretical basis of the technique is discussed along with possible practical implementation. Satisfactory results has been achieved.
