摘要

从稳态条件下铥离子光纤的速率方程出发

得到掺铥光纤中光速减慢传输的时间延迟和相对调制衰减的数值解析表达式

利用数值求解法分别模拟计算了在大功率信号和小功率信号条件下的光速减慢传输。相对于小功率信号

大功率信号情况下的相对时延、时间延迟和群折射率都比较大

同时最大相对时延也向高频率处移动。

Abstract

According to the transition rates equation of Tm ion under stable condition

the analytical expression of time delay and the relative modulation attenuations was established. The time delay and fractional delay of slow light under different input power were calculated based on the numerical analysis. It is concluded that the larger time delay

the fractional delay and group refractive index can be obtained under high input power of signal. It is also observed that the peak position of the maximum fractional delay moves to high frequency.
