摘要
光纤中的受激布里渊散射效应限制了调幅有线电视(AMCATV)外调制传输中的最大注入光功率,这对有线电视传输是不利的,因而必须采取措施抑制。通过对激光器抖动法进行理论分析,导出了激光抖动法提高受激布里渊散射阈值的公式,实验结果和公式计算是一致的。
Stimulated Brillouin scattering (SBS) in optical fiber limits the maximum launch power of Am CATV externally modulated transmission system, for the reason it must be suppressed. The authors present the theoretical analysis on laser dithering and give the formula of SBS threshold increased by employing this method. The experimental result agrees well with the formula.
