由于光纤慢光在实际中的应用价值引起广泛关注.技术手段上利用相干布居振荡效应实现光速可控更具有优势.本文主要介绍了利用相干布居振荡效应(CPO)实现掺铒光纤中的光速减慢传输,通过改变掺杂浓度、光纤长度、入射信号光及抽运光功率等参量,具体研究了亚稳态粒子振荡和时间延迟的关系.研究结果表明:选择高浓度光纤、增加光纤长度、关闭抽运光源,选择适当强度的信号光可以有效地增大时间延迟.
Due to the fact that the application of slow fiber in optical fiber has drawn wide attention in practice, it is more advantageous to utilize the coherent population oscillation effect to control the speed of light in technical means.This paper mainly introduces the use of Coherent Population Oscillation (CPO) The relationship between the metastable particle oscillation and the time delay is studied in detail by changing the doping concentration, fiber length, incident signal light and pumping light power etc. The results show that the choice of high concentration optical fiber and the increase of optical fiber Length, turn off the pump light source, select the appropriate intensity of the signal light can effectively increase the time delay.
