摘要: 在描述皮秒脉冲通过半导体光放大器(SLA)动态过程的理论模型中引入SLA增益谱的波长分布和漂移,数值计算了增益谱的波长分布和漂移对放大脉冲实时分布的影响。结果表明,具有相同分布、不同波长的输入脉冲经SLA后,输出脉冲的形状、峰值功率以及峰值出现的时间均不同;在不同的SLA增益下(即SLA在不同的偏置电流下),是否包含增益谱的波长分布和漂移对皮秒脉冲经SLA放大后的分布有显著影响。Abstract: By introducing the wavelength distribution and shift of the gain spectrum of semiconductor light amplifiers(SLA) into the theor etical model that describes the dynamic process of picosecond optical pulses pas sing through the amplifiers,the influence of the wavelength distribution and shift of the gain spectrum on the temporal distribution of amplified pulses is numerically studied. The results reveal that for the input pulses with the same tem poral distribution but different wavelengths passing through the SLA,the output pulses have obvious distinctions in their shapes such as the peak power and the time of the appearance of the peak;under the SLA biased at various currents,the output pulse has obvious differences between including and neglecting the gain shift and wavelength dependence for a input pulse passing through the SLA.
