摘要 利用色散位移光纤中的复合非线性效应 (自相位调制、四波混频、交叉相位调制 )得到重复频率 10GHz、谱宽大于 5 0 nm的超连续 (SC)光谱 ,研究了泵浦光功率、波长与生成的 SC光谱宽度和平坦度、光脉冲质量的关系。利用 AWG从 SC谱中滤出 4个 10 GHz不同波长光脉冲。 WT5”BZ]:In this work,10 GHz bandwidth over 50 nm supercontinuum (SC) generated from a dispersion shifted fiber resulted from combined effects of SPM,XPM and FWM.The influences of several parameters on bandwidth,flatness of SC and quality of pulses are investigated.10 GHz Four different wavelength pulses was filtered from SC by applying AWG.
