我们报告了一项使用单个掺铒光纤放大器进行低功耗驱动光限幅的10 ghz和高精度脉冲逐脉冲强度限幅的试验。基于自相位调制的光学限制器具有适当的预啁啾，可以在10 ghz比特率下提供小于0.1 dB的高限制精度。对具有强度波动的10ghz比特序列进行了仿真和实验验证。当在2ghz频率下输入1.6 db正弦强度调制时，实验装置成功实现了精度为0.1 db的光限幅。
We report a trial of 10-GHz and highly accurate pulse-by-pulse intensity limiting with a single erbium-doped fiber amplifier for low-power-consumption driving optical limiting. A self-phase modulation-based optical limiter with an appropriate pre-chirping made it possible, which provides high limiting accuracy of less than 0.1 dB at a 10-GHz bit rate. The limiting function was tested in a simulation and an experiment for 10-GHz bit sequence with intensity fluctuation. When fed a 1.6-dB sinusoidal intensity modulation at 2 GHz, the experimental setup successfully achieved optical limiting with 0.1-dB accuracy.
