基于光纤受激布里渊散射的慢光延迟研究

Research on slow light delay in optical fiber based on stimulated Brillouin scattering

针对光纤中受激布里渊散射的慢光延迟进行了实验研究。分别利用标准单模光纤(SSMF)和高非线性光纤(HNLF)在毫瓦量级的泵浦功率下实现了纳秒量级的慢光延迟,并通过实验测量了泵浦功率对慢光延迟的影响,得出在一定泵浦功率范围内才能得到理想的慢光延迟的结论。

For optical fiber stimulated brillouin scattering in the slow light delay, the paper made experimental study, respectively, using standard single-mode fiber （SSMF） and high nonlinear optical fiber （HNLF） under the pump power of milliwatt magnitude realized the slow light delay nanosecond order of magnitude. By mea- suring the effect on slow light delay of using different pump power in the experiment, it came to the conclu- sion that slow light delay can only be achieved under a certain range of pump power.
