基于高非线性光纤中SBS效应的慢光系统

Slow light based on stimulated Brillouin scattering in high nonlinear optical fiber

摘要:

实验研究了高非线性光纤(HNLF)中受激布里渊散射(SBS)的阈值、增益谱、放大特性及其慢光特性,并与普通单模光纤(SMF)进行了对比分析。测量实验表明,HNLF在线宽100MHz的泵浦激光作用下,SBS的阈值为60mW,增益带宽为150MHz,获得的最大慢光延迟量将近15ns,延迟谱与增益谱较好对应。对基于SBS的未来全光通信系统中的高性能光延迟线或全光缓存器具有重要的参考价值。

Abstract:

The Stimulated Brillouin Scattering(SBS) threshold,SBS gain spectrum,SBS amplification characteristics and slow light effect based on SBS in high nonlinear fiber(HNLF) are experimentally studied and analyzed.The SBS threshold and gain spectrum of a standard single mode fiber is also measured as a comparison to that of the HNLF.Under a SBS pump light with 100 MHz linewidth,the SBS threshold of the HNLF is 60 mW,the bandwidth of the SBS bandwidth gain spectrum is 150 MHz,the maximum delay experimentally achie...
